Can't log in

I used to be able to log in with my main account (not this one), but I can't seem to log in anymore. It has been a few months since I logged in with my main.

Nothing happens when I sign in through Steam. I've joined the WGN Steam group already. I tried Chrome, Chrome Incognito mode and Firefox, but nothing works. I just get redirected to the original page with the "Sign in through STEAM" button and nothing changes.

Today, I made this alt account just to see if it works and it logs in to WGN without any issue.

What's the problem?
