Game Freezes and won't "Catch up"

Generally after about 8 min an online game will begin to "shudder", possibly due to a lag spike or PCU spike, sometimes it does not recover. The game will infinitely attempt to "catch up" with no ETA and never will catch up (I have waited ~5 min after pausing immediately). The game then puts me AFK after the timeout. This never happens in single player. I can still chat and pause the game with the keyboard, but I cannot actually "see" that happening.

I know I'm not the only one this happens to, I have had a friend have this problem for years. Due to this never happening in single players I highly suspect this is a network thing, almost like a desync. Nothing about my network has changed to make this begin happening, but either way the game should catch up even if I desync. It began happening after a few game updates ago.

Going back to lobby and re-joining is the only way to fix this and even then it's about 10% chance if it will hang-up on that same point in the game.

I had that yesterday for the first time.

I think it happened just as a nuke hit after perhaps 30 to 40 minutes gameplay, the game appeared hung for ages, then I waited for the server to catch up, which was like 40 minutes !

35 minutes of waiting, and then the game ends..

Looking at the logs, it seems like it see's 2 games:

It was on a busy Sunday, as such, the internet is always under stress, but first time I'd experienced this issue.
