CONNECTION FAIL PROBLEM WITH KENWOOD TM-V71

[sv1oz]

Hello,
I have a problem the last two days with my remote rig Kenwood TM-V71
When I turn on the radio it turns on and I have control of it for 5-7 seconds.
After that all controls  freeze but display keeps on  (light,display and also sound),but no further control is possible.
In two minutes I have an audio alarm that connection failed and then display- Radio shuts down.
In status menu if I check locally I can see a SIP error instead of connected or some times "connection failed".
In the beginning it shows "connected"  but after a while when freezes shows "sip error"
I tried to restart router and change lan ports but nothing.
Every time I turn ON it has always same result

Any idea ?

If you  get SIP-error then you have some trouble with your Internet connections or routers, nothing that the RRCs can do about it

In a few seconds have the sound of disconnection and the rig shuts down.

It seems that both routers run ok as the internet is working ok on both of them.

Can you please advise what else to check as this issue getting me crazy and really don't know what to do
