It's fascinating, the errors - now I get this one, basically saying it can't reach the server:

just a few tries later - it simply logs me in.. it is just unreliable.

Hi,
My issue (which usually gives a 'connection refused') is certainly reproducable - just not 100% of the time. Right now, the client is refusing to connect, but I bet if I try in 10 minutes, it'll work. Sometimes it fails right away, sometimes it's stuck for a minute or 2 logging in.

I ran a traceroute on api.faforever.com:

Seems somehow along the way, I do get blocked, and it's not my computer or network doing the blocking. Yet https://downforeveryoneorjustme.com/api.faforever.com says the server is up, so it's my ip that gets blocked perhaps?

Just now, the client logged in, but then is stuck in a weird limbo way:

As I otherwise have no network issues, it does seem there's something in the faf client or server. I now have a hanging client, so there's that. After killing it - it logs in without issues. Traceroute still gives the same outcome.

It all seems magic to me

If there's anything I can run locally to help track down the issue, just let me know.

@brutus5000 said in Login issue: keeps giving connection refused to api.faforever.com:

Connection refused is a general problem on your computer. Maybe some antivirus or firewall software blocking the access or maybe you didn't allow the client to use the network.

Strange, as it works sometimes, just not all the time. I have no anti-virus running, but I'll look at the firewall side of things. Still that would not explain that it sometimes, but not always, fails.

Anyhow, I assume from your reply that the FAF servers aren't blocking me.

Hi crew,

Every now and then the client refuses to let me log in - it gives the connection refused error below, and gives me the log in with browser window. There I can log in, authorize, get a nice "login successful" but in the client I get back to the same error. Sometimes, after 2-3 times of trying, it goes through, other times after 10x trying it still doesn't let me in and I give up and play something else...

This started last week or the week before - didn't have it before that. Any clue what causes this? Server too busy? Something getting blocked somewhere?

I run the latest client as of now 2022.8.0 and after typing all this it just finally logged me in (...) but I still post it as I'm sure it'll happen again
