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. [https://meta.discourse.org/t/discourse-updated-from-admin-not-working-after-rebuild-fatal-502-error-after-rebuild/200443?u=cookieman768](https://meta.discourse.org/t/discourse-updated-from-admin-not-working-after-rebuild-fatal-502-error-after-rebuild/200443) > [@Cloudflare template broken again](https://meta.discourse.org/t/cloudflare-template-broken-again/200219): > > This is a similar issue to [Issue with Cloudflare template](https://meta.discourse.org/t/issue-with-cloudflare-template/35113), 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… ```plaintext 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. --- _[View the full topic](https://meta.discourse.org/t/issue-w-nginx-after-updating/216262)._
