Hi there,
I updated my UrBackup Server on Ubuntu 24.04.3 LTS (GNU/Linux 6.8.0-88-generic x86_64) from version 2.5.33 to 2.5.34 (noble amd64). I also updated my Client on Windows from 2.5.25 to 2.5.26 via the internal update tool. Since then the Client doesn’t connect to the Server anymore. Neither the new 2.5.26 than the old client 2.5.25 on my other Windows PC. I didn’t change any config files manually.
I installed Wireshark on my Client-PC (Client with 2.5.26) and I can see the Broadcast Messages from the Server:
7080 99.868850 192.168.178.XX 255.255.255.255 UDP 60 35623 → 35622 Len=1
but there is no reply from the Client.
This is the client (debug) log:

after that the last line is repeated every second but no message about a discovery of the Server…
I also tried to reinstall the client from the UrBackup webinterface but no changes.
Thank you for any help
Greetings Alex
