We moved our server from one VPS provider to another and I upgraded the instance via launcher rebuild to the latest version as well, from 3.5.0.beta3 to 3.5.0.beta4. The instance was always running fine behind Cloudflare, but now trying to access it leads to endless 5 dots loading animation. I hav…

I imagine just from the name “Cloudflare Automatic HTTPS Rewrites” it can be misunderstood. Cloudflare has 2 features: “Always Use HTTPS” redirects all plain HTTP requests to HTTPS, just like force_https in Discourse does. Both were previously enabled, and I disabled both to test whether HTTPS has…

Interesting problem. It’s simply https://www.dietpi.com/forum/ that is hanging forever. $ wget https://www.dietpi.com/forum/ --2025-05-03 10:52:18-- https://www.dietpi.com/forum/ Resolving www.dietpi.com (www.dietpi.com)... 104.21.12.65, 172.67.193.183, 2606:4700:3035::6815:c41, ... Connecting to…

Interesting indeed. I recognize just now that the HTML documents are not loading completely but hang at some point. I compared /forum/ in both cases and thought they were identical, but probably I was focusing too much on the head, while parts of the body at the bottom are missing. That last line w…

Do you have some optimization enabled?

Nope, no (content) optimizations. I did have the 103 Early Hints feature enabled, but disabled it already as attempt to solve things. Tried the same with the protocol settings, but that did not change anything eiher: <a class="lightbox" href="https://d11a6trkgmumsb.cloudfront.net/original/4X/7/c/8/7c86cbb6a43d61ccd432fc07d697744f5e9f2ecb.png" data-download-href="/uploads/short-url/hLC0iSeYJcHU6ODIIGS23JEdglZ.png?dl=1" title="The image shows a settings page for HTTP/2 configuration, including options that highlight HTTP/3 with QUIC and Enhanced HTTP/2 Prioritization, with a prompt to upgrade to a Pro plan for the latter feature.

[изображение] MichaIng: Yeah each page/HTML document hangs at the very same character when loaded via browser again and again, in private window etc. I think that might be buffering. But when investigating, I noticed something else. wget -O - https://www.dietpi.com/forum/latest Ends with …

Yes, wget always downloads the whole document, and curl does so when printing directly to console, but connection is not closed. Same happens with much smaller documents, like I tested a 14k one of a topic with only 2 posts. But even the smaller ones usually are not fully downloaded by curl when pip…

I tried all combinations of supported HTTP (1.1-3) and TLS (1.2-1.3) versions, but that does not make a difference. I also disabled HTTP3 support, HTTP2 origin requests this 0-RTT connection resumption again. No difference, curl keeps hanging at exactly the same 73,728 bytes of https://www.dietpi.co…

Could you try KeepAlive Off in Apache? [изображение] MichaIng: I could enable the TCP listener to make the Discourse instance additionally available without the proxy (leaving the Nginx within the container, of course). I guess that would at least possibly rule out the webserver, so that wou…

[изображение] RGJ: Could you try KeepAlive Off in Apache? No change. Also from Apache docs: In addition, a Keep-Alive connection with an HTTP/1.0 client can only be used when the length of the content is known in advance. Hence as of missing content-length probably it makes sense that it …

Are you by chance using RocketLoader in CloudFlare? I know with some other scripts it causes issues. Also, did you clear the CF cache? Are you using inbound rules on CF that may have been tied to your old VPS IP address and not updated to the new one?

Можете попробовать KeepAlive Off в Apache?

Думаю, это хотя бы частично позволит исключить веб-сервер из списка возможных причин, так что попробовать стоит.
