Error 500 & 520 - How to change

Hello,

I’m not familiar with the subject and I didn’t find useful and comprehensible info in the database on how to fix this.

My webhost said that Cloudflare pointed to the wrong DNS address (and gave me the correct one). Then, I logged in here to find these two errors.

I have no clue on what to do to repair this. Any ideas? Thanks in advance.

Greetings,

I am sorry to hear you are experiencing an issue with your domain name while using Coudflare services.

In terms of the errors you are experiencing, may I suggest below articles for more useful information how to troubleshoot them:

Can you be more specific which one of the above 5xx listed does occur at your Website?

Furthermore, may I ask you to share your domain name so we could check out?

In terms of an 520 error:

Hello,

Thank you for your quick answer. The site chirurgie-ge.ch is currently down, due to a Wordpress plugin actualisation conflicting with my theme. I deleted this plugin. However, it seems that Cloudflare didn’t like the site being offline. Right?

Here is the cdn-cgi/trace:

fl=100f25
h=chirurgie-ge.ch
ip={redacted}
ts=1643049047.077
visit_scheme=http
uag=Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.137 Safari/537.36
colo=MUC
http=http/1.1
loc=CH
tls=off
sni=off
warp=off
gateway=off

Currently I see the error, but coming from WordPress, not Cloudflare:

I would suggest you to enable WordPress debug mode and troubleshoot this first with your hosting provider.

And you are running an old unsuported PHP version (maybe missing some PHP modules too):
x-powered-by: PHP/5.6.40

The error 500 what you see is coming from WordPress so far for now.
