Hi. Thanks for the fast reply.

Here it is:

Thank you, all looks okay on the account. Are you able to connect to a mobile hotspot or VPN?

7

Unfortunately i do not have VPN, but connected through the Hotspot via Wifi, and the result was the same. I was unable to pass the backend error promt.

Also worth noting is the fact that all the game frames including loading windows, laucher windows are sorrounded with Green frames.

Those green frames happened before and after new install.

Thanks for trying. Could you share your most recent console log with us, please?

9

Im affraid i can’t. Once reinstalled i do not have any logs that i could provide. The catalogue is empty.

10

Each time you close Darktide, a new log should be created - do you still have the client open? If so, please close it. :slight_smile:

11

No log was created. Im out of game client, steam client etc.

12

Have you exhausted every solution here, or are there some remaining that you could try? :sweat_smile:

I had followed the steps of the article, but nothing helped. Yesterday the game worked perfectly fine, but once the patch was installed i could not access the game. I will reinstall it, and try getting the logs, but as im launching game it doesnt create the logs nor Roaming files at all.

Tried flushing DNS, no change unfortunately. Only other thing I can try is port forwarding I guess.

17

Same issue since patch. Nothing helped so far.

18

I had this same issue last patch. Try closing steam completely and reopening it. Also tried reinstalling steam and that fixed it for a while and then it came back, but closing steam and reopening always worked for me. Hasn’t happened this patch yet.
