Cannot get into us east servers, can't get into friends lobbies

Same exact issue here!!  I use a PS5 and my brother uses PC, we are experiencing the exact issue above. My sons are experiencing it as well, one son uses XBox S, the other on PS5, they are able to get into games together sometimes, not often, but way more often than me and my brother. We all get exact issue stated above.  I'm also experiencing a 'pre-processing' message when trying to queue up just myself.
