Unable to connect to online game — "Your session timed out from inactivity"

Hello,
I’m experiencing an issue that prevents me from connecting to the online game.
Each time I try to join a match, I receive the following error message:
"Your session timed out from inactivity, you've been disconnected."

This issue started right after a short power outage at my home, which caused my PC to restart.
I have already tried the following steps:

Restarted my PC and router

Waited about 30 minutes before reconnecting

Verified my internet connection (it’s stable)

Unfortunately, the problem still persists.

For reference, I’m playing Battlefield 6 via Steam (not the EA App directly).

Could you please advise how to resolve this issue?
Thank you in advance for your help.
