What it says. When i open the client i get an error and it takes a while for the login thing to pop up. Once i enter my information, it just resets giving me the error again and making me enter the info all over again. Not sure what to do at this point. Here's the error:

Update to the latest version it has better logging so I can see what is going on. https://github.com/FAForever/downlords-faf-client/releases/tag/v1.6.0

0

Shouldnt the client update automatically? Regardless, im not sure how to update it manually (i downloaded the source code but idk what to do with it)

There is an installer exe dfc_windows-x64_1_6_0.exe on the page I linked. And no fully automatic installs are not implemented yet.

0

Ah got it. Ill install it and see if it improves

0

Okay i just tested it and there was no error this time: it logged me in automatically. Thanks!

Okay, i spoke too soon. The error started occuring again, or at least a similar one. Here's the log just to be sure:java.util.concurrent.CompletionException: org.springframework.web.reactive.function.client.WebClientRequestException: failed to resolve 'api.faforever.com'; nested exception is java.net.UnknownHostException: failed to resolve 'api.faforever.com'

This error is different and I have seen a few people with it. From what I can gather the issue is that the dns you use fails to resolve the api.faforever.com website for some reason. In your case it is clearer that the issue was a time out after 5 seconds. DO you have slow internet?

I am trying to find the root cause of these issues and it is good to have more info about system config.

I am investigating why this is happening to some users and actually just made a beta release aimed at resolving this which you can try. You can download it here https://github.com/FAForever/downlords-faf-client/releases/tag/v2021.10.0-beta . Let me know if it works for you

@sheikah thank you, changed network's dns to auto, resolved my problem with:

sure:java.util.concurrent.CompletionException: org.springframework.web.reactive.function.client.WebClientRequestException: failed to resolve 'api.faforever.com'; nested exception is java.net.UnknownHostException: failed to resolve 'api.faforever.com'

@tonx92 so you changed your network dns and the issue resolved? If I may ask what was it set to before? Trying to understand what causes the issue in the first place.

0

@sheikah i think in my case it only my dns problem, earlier i using custom dns ip address, for working in my client's vpn network, and forgot abort changes after complete.
I suggest, that problem "can not resolved api.faforever.com", may be resolved by changing user's network settings for using dns from CloudFlare or Google.

CloudFlare DNS
dns1_ip_v4: 1.1.1.1
dns2_ip_v4: 1.0.0.1
Google DNS
dns1_ip_v4: 8.8.8.8
dns2_ip_v4: 8.8.4.4

Additional: it can increase connection quality in game and decrease ping.
