This is the same error as shown here Community Tip - Fixing Error 525: SSL handshake failed.
But it is not our servers or at least if it is there is some weird thing happening for 1-3 minutes each day because the rest of the day it works fine.
We use digital ocean with a load balancer, which doesn’t handle SSL but each origin server does. The SSL we are using is Full (strict) using the Cloudflare Origin CA certificate on every server. We also have another server which doesn’t use the Cloudflare proxy (to avoid upload limits, but turned into a backup domain because of Cloudflare issues) and it works fine while these issues are happening, which leads me to believe this issue is not on our side.
I was thinking of using Cloudflare’s load balancer, but I don’t even know if that would avoid this issue since I assume the same connection would be occurring.
My other option is to just go back to having the origin servers use letsencrypt instead of the Cloudflare cert.
I have checked every log possible and I have never had any form of error. The only thing I see is traffic drop to 0 while the error happens.
