blackboxes don't connect anymore

[DL2MIJ]

Hello first...
Previous story : i have been operating a YaesuTwin system for a few years now.
Until yesterday evening it ran without any problems
But now the blackboxes don't connect anymore.
i can open the config page, even on the antenna side via laptop and anydesk.
so the 2 blackboxes are running as usual.

Is something wrong with remoterig.ddns ?

maybe someone can suggest a solution, i would be grateful in any case.

I was perhaps a little panicky ?!
It works again in any case .
I haven't changed anything. I don't know why no connection was possible for a few hours.
