@neziwo Thanks, was having the same problem and your workaround help me as well.

A few others have reported it here within the past few hours as well- https://downdetector.com/status/ghost-recon/: (https://downdetector.com/status/ghost-recon)
Having no other internet issues. The game tells me I'm connected to the servers but stays on the connection screen, then utimately returns the 01100 error.

Also validated all files, reported crashes... No way I'm downloading this turd again though.

@Ubi-TheBerry

Yes I did try that, no it did not work.

Same issue, crashes during loading screen. This is the first time I loaded the game since the last update. The game tries to synchronize saves after the crash but fails at that as well.

Seems to be working now.

@DraCleave Yeah, the server issue only seems to be impacting Breakpoint. I can connect to Wildlands and other Ubi games just fine.

After 20+ hours of post-purchase gameplay and countless cycles of clound sync off/on along with the other things I tried, the Season Pass content finally showed up with an in-game notification.
I doubt anyone is listening, but this experience doesn't inspire me to buy more Ubisoft products, on sale or not.

I can't get all the content from the Season Pass to show up in-game after installing. I tried uninstalling and reinstalling the No Compromise DLC. I was finally able to get the Moscow Gambit and other missions to show after joining a several online missions thanks to info in another recent thread, but the air shotgun, stun sniper and themed clothing content are still missing. Any ideas on what to try next?

Edited to add: this is on PC, both the game and DLC were bought through Ubisoft Connect. I have roughly 20 hours of playtime since the installation of the season pass. I've also tried going on- and off-line in the game to force refresh, disconnecting in game overlay, uninstalling all of the DLC and then installing No Compromise DLC alone, playing another 4 online missions, completing all of the Moscow Gambit missions, nothing works.
