I have a Wordpress site calci-patrimoine.com that has 520 errors every now and then. There for example, by emptying the wordpress cache, I get this page. I contacted my networks admin to see if there is anything he can do. But I find myself stuck. I followed the Cloudflare procedure but nothing helps.
@nico59821 , according to Cloudflare, you must be hallucinating. The issue with intermittent 520 errors was thoroughly investigated and “fixed” by Cloudflare. The thread discussing it was closed even though most posters (including yours humbly) continued to get those errors after the “fix”: Sometimes a CF 520 error Opening a ticket doesn’t help much: after you provide details, they don’t answer for a week and then switch back to their canned response of " Error 520 is essentially a catch-all response when something unexpected happens or when the origin server incorrectly interprets or does not tolerate a request bla bla bla". AFAIK, most sufferers simply stopped using Cloudflare - the only working solution available.
Due to the number of 520s being reported in similar circumstances, we are escalating the issue to Cloudflare Support. The original incident should have been resolved and your issue may well be unrelated.
We recommend checking these troubleshooting tips, if you haven’t already.
If you have been through these thoroughly and are not seeing corresponding issues on your network/server and you have a ticket number with Cloudflare, please reply and post that #.
To enable efficient troubleshooting by support, please ensure you include the following on the ticket:
example URL(s) where you are seeing the error
Ray IDs from the 520 pages
output from a traceroute from any impacted user
output of example.com/cdn-cgi/trace - replace example.com with the affected domain.
