Hello,
Since this morning at 2:30 am I’ve been getting random 520 errors on my domains configured with Cloudflare proxy on cluster130 using the France IP; on the domains with the CDN IP there are no issues.
On my other hosting on a different cluster there are no issues either.
Is anyone else on cluster130 also using Cloudflare in proxy mode? If so, are you experiencing the same random 520 errors?
Hello @EmmanuelM1
Could you disable the "proxied" option in Cloudflare to see if the anomaly is still present, please? This option is not compatible with OVHcloud SSL, and support recommends disabling the latter.

Hello @Asterix
Sure, if I remove the proxied setting it works, as I said this morning the problem comes from the proxy.
But it's been working fine like this for years.
For SSL I set it to flexible precisely so that it sends the requests in HTTP to OVH
Hi @EmmanuelM1
Just as a test, have you tried changing Cloudflare's SSL mode to Full instead of Full Strict?
Let us know, best regards.

rien à voir lol
if I do that nothing would work, no SSL at OVH...
anyway, this morning around 2 am my alerts stopped, so a little OVH robot must have fixed the script/firewall on one or more servers that had been misconfigured the night before.
