It’s not working from here. My site is experiencing a similar error as well except it’s not showing error code 523 but 521. Could this be a CloudFlare error?

As mentioned in the other post, have you checked this?
Yes, the IP corresponds. I used a CNAME so that the IP corresponds everytime. It frequently works and fails at the same time.
I can access the login page but after logging in I get that error, refresh and it’s gone - system works fine, then the next moment it’s the same error 521.
I’d say it’s unstable.
