My game was absolutely fine a few months ago, I have returned to Destiny 2 now and I can join the game for around 20 seconds then I kicked with the WEASEL error. I have been through the advanced network troubleshooting and have confirmed UPnP is enabled but regardless I tried port forwarding and even a vpn and I am still getting the error constantly. Beforehand I just installed the game and it worked so what could have changed? EDIT: Tried resetting my IP address and still nothing.
