Yeah, still having the issue signing in. I just tried again and received the same error. I first tried few hours ago and got the error message, thought it was Hive Keychain issue, but I bought a few LEO tokens and the transaction went through.

The "request timeout" message pops up after few seconds within the time frame given to sign in.

I still have the same issue with Rafiki curation site, not able to sign in.
