Steam Register Fail: steam: wrong ns in the response

This is new, and just started happening today. I am already registered for a championship, and I try to register again to change the skin. It gives me this error:

“steam: wrong ns in the response”

and in red:

time="2025-02-11T21:29:37-05:00" level=error msg="Couldn't load ACSR rating for guid: 76xxxxxxxxxxxxx" error="crypto/aes: invalid key size 0"time="2025-02-11T21:30:08-05:00" level=error msg="Could not validate steamID" error="steam: wrong ns in the response"

I’m running ACSM Premium v2.3.9 on linux.

Any thoughts?

And now it’s working again? This is weird.

Note it happened to me on my home computer, work computer, and phone when I tried to (re-)register.

Hi,

This was an issue with the Steam OpenID login API that affected all “Log in with Steam” systems, as discussed here on the Steam forums: Steam openID broken? :: Help and Tips.

Unfortunately in these scenarios all we can do is wait for the API to come back online, although these incidents are very rare.

Thanks!
