I recently switched to SSL Certificate and DNS Proxy.
Everything works well so far. But every now and then the performance drops for a few minutes and there are 502 timeout errors. But only from one computer. On another computer the performance is great in the same time.
We have our CMS system on the domain. For the url, we have deactivated the security and performance with the roles. But it does not help.
Before, we did not have the problem with the performance.
Can someone help?
i have a valid origin certificate from cloudflare installed on my server and have SSL/TLS encryption in Full mode (strict).
I cant explain what is wrong. It only happens for a few minutes now and then. The page no longer loads.
Is it SSL, Cache or Proxy problem?
Though if you say it is only from one connection, then you might use a different PoP there and if you only experience issues there that would most likely suggest your server is blocking or limiting certain Cloudflare datacentres. That’s something you’d need to discuss with your host.
If it works with the firewall disabled the issue will be the firewall and that it will do exactly what I mentioned before. In that case you’d need to go through your logs and check what it is blocking and make sure everything from cloudflare.com/ips is whitelisted.
