Re: "An unknown error occurred. Error code: 1" Since Dec. 1, 2023

Can't join servers, reports "Error code 1 Failed to join the session". Server browser lists just 4 full servers.

Since a few weeks I am unable to enter most servers due to the game giving me an Error Code 1: Failed to join the session. This happens both when I attempt to join via the server browser or via matchmaking.

Also the server browser is only showing 4 servers (always full with large queues when I checked) even though I filter only on game mode Operations, region Europe and Hiding empty servers. Oddly when I refresh the server browser a lot, eventually it will show one additional server that is being populated (having more than a few players in them), but when I join that one it gives me again Error Code 1.

It seems I can join the mentioned 4 servers (after being queue for a long time).
Matchmaking usually also gives Error Code 1 but sometimes it will put me in a server in the USA (I am region europe).

Naturally I first attempted to fix it before reaching out here. What I have tried so far:

But nothing has changed the situation.
I am 100% confident there are more than those 4 servers, which is being supported by server browser sometimes suddenly showing a server with e.g. 8 players, which I can't join and is gone with next refresh. I fear there is somehow something wrong with my account or something

Any help or suggestion is greatly appreciated. This is my nr1 favorite game shortly after it came out. I really want to get back in there.

    I hate modern day Google. That would have been a useful search result, but I'm not getting it.

    Anyway... maybe.
    Why is the server browser so erratic and it sometimes shows me a populating server (which in turn I cannot join).
    Well, guess it doesn't matter and its just part of the bug DICE introduced.

    Sure takes them long enough to fix it though.

    Thanks for the heads-up.

    Yeah, the serverbrowser can be a bit buggy but at least there is one in BF1 :D

    If there are 10 players in queue for a server, you cannot join the queue and will receive a message like "Server is full". I would suggest you try the quickjoin function for the gamemode you wanne play to find a server or until EA/DICE fix the bug go to US East servers.

    @Smoker_Sally Yeah that can work but most of the time you'll end up with the same code.
    I wonder if there is gonna players enough after the fix to fill up the empty servers ☹️
