Issue w/ nginx after updating

[cookieman768]

Hello - I just updated my installation today but, I encountered the following error, and it keeps repeating. I’m unable to access the site but, it looks like this should have been fixed earlier this year? These two posts seem to have the same issue, but I’m not sure what changed to break this again.

Discourse updated from admin, not working after rebuild. Fatal 502 error after rebuild

My current website Discourse was on [image] I did a admin upgrade when it showed me this, [image] Admin upgrade from UI worked fine and no issues found. but After that when i did rebuild, and when i goto my site on browser, it says Host not found and my site was not working. Now our site is broken forever whenever we do rebuild and we r not able to bring back our site. Now i had an older droplet, so i restored from my older DO droplet snapshot, and now site is up but when i am trying to res…

Cloudflare template broken again

This is a similar issue to Issue with Cloudflare template, but this time Cloudflare appears to have removed the trailing line break from the IPv4 list, resulting in the following output (comment added to indicate problem): set_real_ip_from 173.245.48.0/20; set_real_ip_from 103.21.244.0/22; set_real_ip_from 103.22.200.0/22; set_real_ip_from 103.31.4.0/22; set_real_ip_from 141.101.64.0/18; set_real_ip_from 108.162.192.0/18; set_real_ip_from 190.93.240.0/20; set_real_ip_from 188.114.96.0/20; set_r…

nginx: [emerg] host not found in set_real_ip_from "131.0.72.0/222400:cb00::/32" in /etc/nginx/conf.d/discourse.conf:116

Has anyone else encountered this? I’m just not sure what the fix would be unless something changed with Cloudflare yet again.

I would say to make cloudflare dns only or at least disable all optimization.

Next

cd /var/discourse
git pull 

And see if it succeeds.

So, like change it on cloudflare to be DNS only?

Hmm, yeah - it looks like the nginx: [emerg] host not found in set_real_ip_from "131.0.72.0/222400:cb00::/32" in /etc/nginx/conf.d/discourse.conf:116 is still being spammed in the logs even after setting Cloudflare to DNS only. If anyone has other troubleshooting ideas, I’m all for it!

EDIT: I think I found the culprit - there was a custom commands section at the end of my app.yml it looks like in newer installs this is handled by the template. I’m commenting it out and using the template.

EDIT 2: Yeah, it looks like I installed Discourse before the template came out so my template was in the app.yml, simply removing it from the app.yml and using the template fixed it. Thank you for the help @pfaffman!
