Whenever we turn on proxied mode we get a web server down (error 512) error. I have googled a lot in this forum and we tried multiple things without luck:
- Web server is responding on HTTPS (443) without CloudFlare
- Universal SSL has been turned off then turned back on
- Purge All Cache has been used many times
- Tried all SSL/TLS encryption mode available
It seems opening support ticket is not possible anymore. My domain is “onecdn.org”. Could somebody have a look and advise?
SOLUTION: I switched SSL from flexible to full (strict) and then solved the problem though I tried it previously and didn’t work so weird.
