I use cloudflare for my forum for multiple reasons, but I want to get the real IP of my visitors so I can get accurate data of how many people are signed up with that IP address, and so IP banning, etc works. Is there any way to do this?

Looks like the cloudflare template is broken at the moment. Last update was in 2016. Please remove it and rebuild. I will take a look at fixing it, time permiting.

You need to add cloudflare.template.yml to your app.yml file templates section.

If I visit the forum it just gives me a Error 521 Web server down.

That is the database log. Can you check the logs at /var/discourse/shared/standalone/log/var-log/nginx/error.log ?

error.zip (123.2 KB) The error.log file is in this zip file, It’s mostly just the same thing. (I can’t post the .log file because it’s not supported, and everything in the error.log file as its a super large amount of text)

Alright, thank you for the help!

I’m getting the same issue, glad there is a solution here :slight_smile: Weird thing is that it seems to only be affecting rebuilds done today. Other servers (same Discourse version - Stable 2.7.7) are running ok. Though started getting some strange errors recently on a few forums (not after an update): Oops The software powering this discussion forum encountered an unexpected problem. We apologize for the inconvenience. Detailed information about the error was logged, and an automatic notification generated. We'll take a look at it. No further action is necessary. However, if the error condition persists, you can provide additional detail, including steps to reproduce the error, by posting a discussion topic in the site's feedback category. Not sure if it’s related, the error was why I was recently doing rebuilds on the same version. Edit: Confirmed, removing the Cloudflare template fixed the 521 error. Update: Looks like @Zenexer made a PR for this: Cloudflare template broken again

[תמונה] Falco: Looks like the cloudflare template is broken at the moment. Last update was in 2016. Please remove it and rebuild. I will take a look at fixing it, time permiting. If i comment the cloudflare template line in app.yml, then how would it affect my [site] ?(https://howtodiscuss.com)? we are using cloudflare on our site. Also, is my problem is the same? https://meta.discourse.org/t/discourse-updated-from-admin-not-working-after-rebuild-fatal-error-site-does-not-load-anymore-after-rebuild/200443 @markersocial my site is running on cloudflare if i remove that line, what would happen to my site?

[תמונה] Faizan_Zahid: @markersocial my site is running on cloudflare if i remove that line, what would happen to my site? As far as I know, people will have their registration and recently used IPs logged as Cloudflare IPs instead of their real IPs. So if you ban someone, the Cloudflare IPs will be added to your ban log. Which isn’t good yeah. I believe this will mean users cannot sign in or register if they by chance get one of the banned Cloudflare IPs (while the template is not being used). Users already logged in will not be affected I think. In the past (likely still now, not sure), this could cause even admins and moderators to not be able to log in to a new session. Might be a good call to disable public registrations and not use IP banning until the template is available.
