What is the issue you’re encountering

Hey, I want to host a few webservers on my Raspberry (CasaOS, paperless-ngx, n8n etc.) and reach them from outside my home network. That’s why I registered a domain on Cloudflare, setup nginx on my Raspberry, opened ports 80 and 443 on my network and added a proxy host to nginx. Now I have the problem that it takes ages to load a page. When accessing the page via IP address from my network it loads instantly. When using my domain it either takes ages (30-60s) or I even get timeouts. I’m not too familiar with administrating webservers or anything related to it so I hope for some answers and patience. I’m happy to answer all follow up questions! My setup: - Raspberry Pi in my home network - FritzBox 6591 as router - Nginx Proxy Manager running as Docker container (jc21/nginx-proxy-manager:2.12.1) on Raspberry - IP addresses are updated automatically via Docker deployed cloudlare-ddns

What steps have you taken to resolve the issue?

I turned off Nginx Proxy Manager and put CasaOS behind port 80 and the problems remain the same. The page loads in parts very slowly and can’t finish to load everything within the deadline, thus it looks like a Cloudflare issue.

Hello,

You can begin by investigating if Cloudflare can reach your server. Try removing Cloudflare’s proxy (under Cloudflare DNS settings, change the orange cloud to gray) and accessing your website directly. If the page loads properly, the problem is with Cloudflare’s connection. If not, the issue is with your network configuration.

You may also execute the following command on your Raspberry Pi to ensure that Nginx is properly listening on ports 80 and 443.

sudo netstat --tulnp | grep nginx
