Hello. I linked my domains with cloudflare and everything was working great until a few days ago when my domains became unreachable. Any idea what could have happened? I’m not sure if this has to do with Cloudflare issues (see issue) or my own vps configuration issues.
Error 526 indicates Cloudflare is unable to successfully validate the SSL certificate on the origin web server. Make sure you have configured a valid certificate on your server. See this 526 Community Tip for suggestions.
That site is not proxied as the DNS A record is which means any issue is straight out of the origin.
Both the 526 and 522 errors mentioned are from the origin server. To debug I’d start with contacting your hosting provider to see if they’re seeing the errors in their logs. The tips linked on 522 & 526 have quickfix ideas to guide you on the questions to ask your hosting provider.
The hosting did not give me an accurate answer. He only told me that it was a Cloudflare problem and that they couldn’t help me because I have a VPS service and they don’t support VPS
I tried several solutions that I found on the net like deleting my site from Cloudflare and adding it again and in all cases the error persists. I’m using Cyberpanel by the way.
