Wordpress website live but Wordpress Admin shows 521

[martin62]

Hello there,

I have an issue with a specific website. Every 12h or so I need to reboot the AWS Server because the Wordpress Backend shows 521 error but the actual website is live. How/Where can I check? My UpTime Monitoring Software does not alarm me of the “downtime” because the actual website is working perfectly.

Any hints are welcome

Community Tip - Fixing Error 521: Web server is down

Error Try the suggestions in this Community Tip to help you fix Error 521: Web server is down. Background A 521 error happens when we are unable to make a TCP connection to your origin server. Specifically, Cloudflare tried to connect to your origin server on port 80 or 443, but received a connection refused error. This is often caused by security or firewall software and happens if the origin server has directly refused Cloudflare’s proxy request. [Banner in tip catalog] Quick Fix Ideas …
