So im following this guide to setup a offline page for when the forum goes down for whatever reason but ive run into 2 issues. The two issues im running into are that nginx is not redirecting 502 errors to the offline page and when both discourse and nginx are running i cant reach the forums. [תמונה] Add an offline page to display when Discourse is rebuilding or starting up Sysadmins warning This guide is intended for advanced users, who are already using nginx outside the docker container. By following this guide you make your setup more complicated and will lose some speed benefits like HTTP2 if you’re not running Ubuntu 16.04 or later. Proceed with caution! When Discourse is rebuilding or starting up, your users will usually either see an error message from their browser… [image] …or a not-so-nice 502 error message from Nginx: [image] If you’re a perfectionist … /etc/nginx/sites-available/default.conf https://paste.fedoraproject.org/paste/e01vmM3pkI41nlZhzuDmuA/ /etc/nginx/nginx.conf https://paste.fedoraproject.org/paste/B032qvRECjgrsvcjXCWc7g NOTE: i added the include /etc/nginx/site-available/*.conf; line because it would only load the default config /var/discourse/containers/app.yml https://paste.fedoraproject.org/paste/DQxhGWvfD7MBUyYWGTpqxQ/ Any tips or advice for what i might be doing wrong?

[תמונה] fefrei: However, I also get a 403 when browsing https://forum.cubedcorps.net/errorpages/discourse_offline.html, so there must be some additional problem. Having a look at the Nginx log files might help you here :slight_smile: Selinux was just being a pain still XD [תמונה] notriddle: Are you running with SELinux or AppArmor on the host system? [תמונה] notriddle: Try turning it off, then. Thanks for all your help :smiley: Never used nginx before and this was a great learning experince

Weird! Are you 100% sure you’re talking to the right Nginx, and it is indeed reading the configuration you provide? When in doubt, I tend to replace everything in location / with something like return 410; (or some other unusual status code), checking whether I’m really served that status code.

i am indeed talking to the right nginx. Replacing everything in location / with return 410 results in a 410 error code

Hm, too bad, that’s always a nice and easy explanation :wink: Next, I’d try to debug this: [תמונה] dje4321: when both discourse and nginx are running i cant reach the forums What happens if you try to access Discourse? What do the outer Nginx’s log files tell you about the request? Does anything show up in the log files withing Discourse’s container?

Totally forgot logs were a thing XD nginx access.log when i try and access the domain REDACTED - - [25/Feb/2018:10:30:53 +0000] "GET / HTTP/1.1" 502 173 "-" "Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:58.0) Gecko/20100101 Firefox/58.0" "-" REDACTED - - [25/Feb/2018:10:30:54 +0000] "GET /service-worker-49bb49a79c0c56d327e5dc0c32ba4b6469a79f13f05a5e174c02f8cb5b1df7b3.js HTTP/1.1" 502 173 "-" "Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:58.0) Gecko/20100101 Firefox/58.0" "-" error.log tells a different story 2018/02/25 10:30:54 [crit] 15312#15312: *15 connect() to unix:/var/discourse/shared/standalone/nginx.http.sock failed (13: Permission denied) while connecting to upstream, client: REDACTED server: forum.cubedcorps.net, request: "GET /service-worker-49bb49a79c0c56d327e5dc0c32ba4b6469a79f13f05a5e174c02f8cb5b1df7b3.js HTTP/1.1", upstream: "http://unix:/var/discourse/shared/standalone/nginx.http.sock:/var/www/errorpages/discourse_offline.html", host: "forum.cubedcorps.net" nothing in the discourse logs

Okay, so something about the socket is fishy. Does the file /var/discourse/shared/standalone/nginx.http.sock exist (while Discourse is running)? Did you rebuild Discourse after modifying app.yml?

Hm, in that case, I’m currently out of ideas. That looks fine, but obviously Nginx is having trouble connecting to it… :thinking:

Are you running with SELinux or AppArmor on the host system?
