iOS Question Push-Problem: Did somebody knows the reason?

[schimanski]

I'm using the firebase-push in my app and the app is in an productive operation, so it is difficult for me to debug everything. On one of the servers, there are suddenly some devices, which couldn't push any longer. The server-logs shows the following exception. Does somebody know, what the reason could be?

Thanke for any help...

It seems like the server is unable to connect to Firebase servers. Might be a network issue.
