No internet connection since update to 24.04-1.1 on FP4

[fairose]

I recently updated to Version 24.04-1.1 on my Fairphone 4. The update went without any problems as always. But since I executed the update, I can't reach websites anymore.

It does not matter if I use the SIM-card or wifi for the connection. I always get an error when I try to reach the internet.
Morph Browser gives me

Error: net::ER_NAME_NOT_RESOLVED

and Sapot Browser gives me

Error: net::ERR_ADDRESS_UNREACHABLE

The browser in Waydroid gives me

net::ERR_NAME_NOT_RESOLVED

However, when I am in my wifi I can reach websites on my local server (192.168.xxx.yyy) without problems. I also tryed to visit 20.43.161.105 (the ip of duckduckgo.com) but that isn't working eighter.
The OpenStore does not load anything. Sending Messenges via TELEports works just fine for some reason. Calls going in and out also work as usual.

Has anyone an idea on how to fix that?
