Error 2004 on loading into hub (Linux, CachyOS)

Warhammer 40,000: Darktide Technical Support
1

Issue Type (Required):

Error - (Other)

Issue Description (Required):

The game works as well as it ever has, but at the loading screen after nearly every match, I’m given a 2004 error and thrown to the character selection screen. Returning to the hub from the meat grinder causes the same issue. Digging through the logs, “Aborting handshake with 9f00fc1f22a93144. Reason: buffer_overflow” looks like a good indicator.

Sorry about this, but we’re unable to provide support for Linux with it being unsupported. There is a small but supportive community of Linux-based players here that may be able to advise.

Don’t fear the penguin, you are able to provide support. The log shows a handshake failure due to a buffer overflow. You can help by providing us info on what causes a 2004 error. Is said buffer on my end or yours?

have you found a solution to this? I’m having the same issues: abnormally long load time + error 2004
