Failed to determine external IP adress

[Mads672g]

I am unable to join multiplayer games with my friend, when they host from their own pc's, and they can't join me when i host.
They have no problem connecting to each other, so the problem is on my end.

When i try to host a game i get the following message:
"Failed to determine external IP adress. Other players might not be able to connect."

22.025 Warning ServerRouter.cpp:492: Received own adddress message reply with conflicting address (got 62.66.207.91:59104, expected 62.66.207.91:59103)
22.026 Warning ServerMultiplayerManager.cpp:551: Determining own address has failed. Best guess: 62.66.207.91:59103

This should be the issue, but ill attach the whole log encase it is needed.

I have the same issue. However I can connect to a server sometime but there is a lot of lag. Seems to be a problem when I connect to my local wifi, when I use 5G its ok. Anyone figured out a way to solve this? Have tried port forwarding but it does not seem to help.
