Title: Radio RRC Web interface does not respond
Post by: oh2xx on 2015-07-24, 11:05:05
Hi,

My remote setup works just fine but the web interface of Radio RRC is quite often unresponsive. I can not even access the web interface on the local LAN there (I have ea remote PC with TeamViewer). The RRC does respond to ping and the radio works etc. but I am not able to access the web page  unless I power reboot the unit at the remote site. Just hate to do it as it reboots everything there: the router, PC, antenna controllers etc.

The RRC SW version  is 2.81

I have also recorded the following error messages if it has something to do with this symptom:

14.7.2015
Data Abort at 0x0004a9dc, called by 0x0004a044

1.7.2015
Data Abort at 0x0004a760, called by 0x0004a72c

17.6.2015
Data Abort at 0x0004aa04, called by 0x0004a044

30.5.2015
Data Abort at 0x0004aa04, called by 0x0004a044

Any ideas?

Karl,

Did you change its web port from 80 to something else? I looks like a port conflict to me.
Then you will need to append :XX with the new port number after the address.

Hi Mitch,

Thanks for the idea but the port number has not been changed. If it was changed even power boot would not help as it does now...

Just try it out to see if it helps. It may solve your problem.

Mitch,

I have not changed the port number so there is no port number (other than 80) to try out ;-)

Have you tried from a different PC ? We have seen a few windows installations where the IP-stack seems to change some parameters so they get really difficult to connect to a RRC with. In such case often parts of the page is loaded but not the whole page. The problem shown worst in combination with Google Chrome, Firefox use to be a bit better. We have not found a reliable solution other than re install Windows

Kari,

Let's try it again.....

Go to the "Advanced Settings" menu on the RRC. Then change "Web server port" to something other than the default 80
which is in there now.

When you access your RRC, give in the browser the RRC's IP number or Dynamic DNS URL followed by :XXX where XXX is the
new port number. If there is a port conflict (since routers usually also default at 80 and cause conflicts), then that will solve
your problem.

Hi Mike,

I have tried with Chrome and IE on both remote PC and my home PC with similar results: "ERR_CONNECTION_TIMED_OUT"

If I power boot RRC it helps. If I power boot PC nothing changes. It kind of isolates the problem on the RRC side - right?

I have noticed that sometimes I get only a part of the web page but after clicking the hyperlinks it kind of refreshes the page and starts to work ok.

My two 1216H Web Switches work just fine all the time.

Mitch,

I can give it a try even though I do not believe in it ;-)  Need to reboot the RRC so it will start to work for some time anyway. Let's see how long the web interface will stay alive with the new port number. With the default port number the RRC used to work a week or two after a power boot.

I am having what seems to be a similar problem.  My RR does not connect (Port 80) and when I try to use RR DNS for a different port that is connected to my IP addressable power switch or another for the camera that doesn't work either.  This has all happened within the last two weeks as my transceiver was in for repair.  No system changes known and going to any computer anywhere home or otherwise has trouble reaching the camera port or power switch using RR DNS as I get a failure to connect. (Doe that mean that I didn't reach the RR DNS or does it mean that I simply can't connect to the device on that port?) Any suggestions on how to test this out? Perhaps my router is blocking this due to an unknown change? Any suggestions on how to test this out?

I am not sure that I understand what exactly you are doing. However, even though Kari doesn't believe in it,
it is very good practice always to change your RRC to another port other than 80. This is to prevent port conflicts
like Kari is likely experiencing, as well as to prevent hackers from easily finding your RRC (you should also add a user
and password). You need to forward the new, unique web port in the router and properly address it in your browser
as described above.

I have a networking checklist available that I send to anyone requesting it when setting their RRC up and this is clearly
explained in my checklist. I consider not changing the port to be a major mistake, due to what I have seen around
what can happen when one uses port 80.

Since it would seem that I am not getting the connectivity where the rig is perhaps your check list would help.  Please email network checklist.  Thank you.

After several checkings this problem is exactly the same in my case. I was using port 8000 and I changed to port 8090 but the problem persist. Looks like a problem with de web server .The only solution seems to be to restart the RRC-Radio on site.

Just for your information. The RRC Web interface has been working now 10 days with the new port number. Seeing is believing but I still need to see more  ;-)

The Radio RRC Web interface stopped responding today. So the different port number did not help. Any other ideas?

Is there anything else accessing the RRC's web server simultaneously? That could make things worse.

The way you describe what happens sounds exactly like what Mike wrote about. In that case the PC is "impatient" and sends TCP reset very shortly after requesting the web page and before the RRC is capable on replying resulting in partially or blank web pages.

A Win8.1 computer at home all the sudden started to behave like that and after a few weeks it suddenly stopped doing that and since then it has worked.

Another computer is stuck at doing that and so it still does not work ok. When a computer behaves like that it also affects for example routers internal web servers causing partially loaded web pages.

So far we have not found out why the PCs do that and we have only been able to improve how the RRC's handles it so it does not reboot most of the time.

Hi

I was suffering from the same issue. I found that in most cases it was due to a very short electricity off/of at my radio location. Only reset (power off for 2-3sec) would help. Added small UPS and ok for 6 months

Hi,

Thank you for your ideas. This is till a mystery to me.

My RRC and remote PC are behind an UPS so that should be ok.

There are not multiple instances accessing the RRC at the same time. It is just me with my home or remote PC.

I still cannot access the RRC either from local LAN (remote PC -  no DNS involved) or from my home PC when this symptom occurs. Both PCs are running Win7 and I find it very hard to believe that both of the PCs become impatient at the same time after two weeks. I am able to connect to the two remote webswitches and an IP Camera all the time. Power booting the RRC helps - power booting PC does not.

Is there a way to send a reset command to the RRC if the web interfaces is unresponsive?

BR,

Kari

We would need access to the unit from here to try debugging it and see if we find something going wrong.

No, there is no remote reset feature available.

I also had similar problems when using W7. Earlier it worked fine but recently it started to behave like Kari has described. I went to RRC advanced settings and set "UDP cmd min-data-size" to 80. That helped but didn't solve the problem totally.

After I upgraded W7 to W10 the problem disappeared.

Jan,

Now testing with the latest FW and changed Eth-type to "Auto" was "Auto prefer 10 Mbit"

Just noticed another symptom if it helps: Sometimes the main page keeps on loading even though the page is ready and displayed. I need to push the stop button in the browser to end that.

Today I got also an error message a few times saying: "TcpError, HTTP: TCP Error: -4, connection=0". Refresing the page helped.

This is not too serious a problem but very inconvenient when twisting the configuration. So I'll keep on testing here and let's see if a closer look is needed.

Pekka,

Thanks for the info - good to know about your W10 experience.

A page that looks "ready and displayed" can still be in a state which is not closed and finished as the TCP communication involves more steps after having transferred that actual page data before being considered 100% finished.

The Error -4 is a TCP Reset which browsers sends from time to time. Internet Explorer is by far the worst of them as it sends them when normally ending a page communication session.

Radio won't start due to lost DDNS info. Tried to reset IP via http://ddns.remoterig.com/status/editip.php but cannot access RRC so cannot find the password to reset the IP. Frustrating. Webswitchs 1 & 2 are responding just fine but it does not help. Need to write down that GD password...
Title: Re: Radio RRC Web interface does not respond
Post by: dj0qn on 2015-09-11, 23:54:43
Kari,

If I understand your problem, you can no longer reach the RRC, due to the DDNS address not working. The following will
help if my assumption is right:

If the Webswitches are on the same network as the RRC, then you can use their DDNS address instead with the correct
port number for the RRC. You only have one, single exteral IP address and you can have a hundred devices all using the
same DDNS address. The only difference is the port number used per device.

I was not able to reach the Radio RRC even via the local LAN as described earlier. This time even the radio did not start and I found out that the IP address had changed but it was not updated  at ddns.remoterig.com . This happens once in a while and in order to update the address manually you need the DDNS password to do that. I usually just go to the Radio RRC and check the password from there but this time it was not possible as it had become unresponsive again.  I was in a hurry when this happened so it was quite annoying. I have now the password stored on my home PC ...

I have similar problem and I think there is a bug somewhere that's why working Rrc web suddenly stop working and with suggestions of other users only hard power disconnect solve the problem there is no need to change ports ,router settings just unplug power from Rrc for 30sec. Plug it back and web working ok so I put a relay so I can remotely "hard reboot "Rrc and were back online
Thanks

By the way icheck different sources accessing Rrc web and nothing works except above method
Title: Re: Radio RRC Web interface does not respond
Post by: dj0qn on 2015-09-12, 15:58:52
Kari,

Please read again what I wrote before.....you only have one, single external IP address. Any device that issues
a DDNS address within the same network will always point to the same, identical IP number. If you have a
Webswitch on the same network that already has DDNS setup, just use that address instead (with the other
port number). I had several devices on my network and always only used the same DDNS address.

This of course doesn't solve your chronic problem of the RRC not being accessible, but solves your DDNS
issue.

Mitch,
This is exactly how I'm using same address for all devices plus port number and web Rrc (plus other devices) has designated port in router settings it works ok for some time then stops I went thru different possibilities and the only way to fix this problem and get Rrc web to work is hard power "reboot"

I sometimes have the same problem.  I connect to the web interface, but nothing shows on the screen.  If I click between Info and status, a screen will eventually come up.  My RRC Radio software is 2.84
