Slow Connection via Cloudflare Proxy from Home Network
Hi everyone,
I’m dealing with an issue where accessing my services through the Cloudflare proxy from my home network is unusually slow. This problem is not limited to one service and affects multiple setups. Here’s a summary of the situation:
1. When accessing my cameras (or other services like my password manager or Nextcloud) via their Cloudflare-proxied domains from my home network, the connection is extremely slow. However, if I use a mobile hotspot or a different network, everything loads normally and fast.
2. If I bypass Cloudflare and directly access my server using its public IP, the speed is fine from my home network.
3. My cameras use a separate Tailscale VPN for their 24/7 recordings, so the Cloudflare proxy isn’t burdened with that traffic. The slowdowns only occur when accessing the web interface to view recordings through the proxied domain.
4. My ISP (Telekom) claims they don’t throttle traffic, but it feels like either Cloudflare or the ISP is limiting the connection specifically when using the Cloudflare proxy.
I’ve tried using iperf to test bandwidth, and while it works fine when bypassing Cloudflare, I understand that such tools don’t typically work through the proxy.
Do you have any suggestions for troubleshooting or identifying whether Cloudflare is contributing to the bottleneck? Are there specific logs, settings, or diagnostics I can use to pinpoint the issue?
Thanks for your help!

The connection between Telekom and Cloudflare is notoriously bad. You'll find a lot of information if you search for Telekom + Cloudflare.
Some people claim disabling IPv6 helps, but it doesn't for me.

If you access your cameras via your home network...
Are they connected to that same network
Yes, but the recordings are on the root server
Thank you for the suggestion! I’ve just disabled IPv6, but unfortunately, the issue persists for now.
Even if disabling IPv6 were to work, I don’t fully understand why IPv6 would cause such a problem in the first place. Could you provide more context or explain why IPv6 might be a factor here?
IPv6 isn't the problem, the problem is the bad connection between Cloudflare and Telekom. But as IPv4 and IPv6 can have different routes, sometimes one works when the other doesn't. Some people have reported IPv4 works better for them. I'm using Telekom myself, and there's no difference for me.
Thanks for the clarification! I’ve now disabled IPv6 in my FRITZ!Box, but I haven’t noticed a significant difference yet. Interestingly, it used to work much better with Telekom before.
Some time ago, I actually called Telekom to enable IPv6 for me. It might be worth calling them again to request disabling it entirely on their end. Hopefully, that might resolve the issue.
I don't see how that would help. You're most likely better off with IPv6 enabled.
I understand your point. You mentioned earlier that disabling IPv6 has helped some people, so I just thought it might be worth testing by asking Telekom to disable it on their end. It’s just an idea to see if it makes any difference in my case.
