I know this is not directly related to Discourse, but since it’s my forum using Discourse, here it is: I’m trying to make sure that all versions of a URL work and direct people to my forum. Those versions are: http://domain.com http://www.domain.com https://domain.com https://www.domain.com www.domain.com domain.com These versions are not working, when Chrome is set to incognito: http://www.domain.com www.domain.com I get this: [image] I’m using Cloudflare and I already created a Rule to redirect domains, suggested by ChatGPT (since I’m not an expert), but it’s not working. Any suggestions of what might be causing this? This is a subdomain like forum.domain.com, not sure if that’s the issue? Because if I use the same format, but with the main domain domain.com, it works. I know this is a very specific scenario, but I would like to make sure that all options in all browser “states” are covered. Thank you!

Oh, you’re already using a forum subdomain. You see this warning about SSL because the free Universal SSL certificate provided by Cloudflare covers only one subdomain level. It won’t work on www.forum.domain.com. I think it’s easier to follow the guide in my first message and let discourse/let’s encrypt (for free) handle www.forum.. What you should do: Remove that page redirection rule Removes the AAAA DNS record with 100:: If you have an existing DNS record www.forum to an IP, remove it Creates a CNAME record www.forum to forum.alltiago.com DNS Only (no proxy) Then, follow the guide, e.g.: [The image shows a code snippet with hooks for modifying file and variable names in a script, used to obfuscate paths involving sensitive information to prevent reverse engineering. (Captioned by AI)] Rebuild, and you’re done! This way: any HTTP request redirects to https://forum.alltiago.com www.forum.alltiago.com redirects to forum.alltiago.com I tested myself on my side, and it’s working great.

This guide should help to setup additional domains with let’s encrypt: Set up Let’s Encrypt with multiple domains / redirects. As for the redirection, it’s handled automatically: templates/web.ssl.template.yml master run: - exec: cmd: - "mkdir -p /shared/ssl/" - replace: filename: "/etc/nginx/conf.d/discourse.conf" from: /server.+{/ to: | server { listen 80; return 301 https://$$ENV_DISCOURSE_HOSTNAME$request_uri; } server { - replace: filename: "/etc/nginx/conf.d/discourse.conf" from: /listen 80;\s+gzip on;/m to: | listen 443 ssl http2; SSL_TEMPLATE_SSL_BLOCK - replace: filename: "/etc/nginx/conf.d/discourse.conf"

I will check this tomorrow, but what I don’t get is that everything works on Chrome and Safari, for example, but in incognito in Chrome, those 2 versions don’t work. So the certificate seems to be working, the one that Cloudflare offers by default. Or am I missing something here?

You can let Discourse handle the domain and certificate by following the guide above. Or, since you’re using Cloudflare, you can also create a redirection from www.domain.com to domain.com; see this tutorial : https://community.cloudflare.com/t/redirect-www-example-com-to-example-com-using-single-dynamic-redirects/636764. [The image shows a web configuration interface with options to create rules for redirecting HTTP to HTTPS and from the WWW subdomain to the root, both marked as beta features. (Captioned by AI)]

Thank you for the link. Following their first instructions, I’m creating this: [image] Their instructions were for the main domain, not a sub domain, so I guess I’m doing it right? When I save, I see this warning icon with this message. Is this normal? [image] Then I go to the rules: [image] Is this how it’s supposed to look like? And does this rule affect when the url has something after the /? For example forum.alltiago.com/tags? They mention that this can take up to an hour to reflect the changes, so I will wait. Let me know if there’s something I missed. Thank you!

[image] Arkshine: If you have an existing DNS record www.forum to an IP, remove it The only things with the word forum (I deleted the AAAA already): [image] [image] Arkshine: Creates a CNAME record www.forum to forum.alltiago.com DNS Only (no proxy) When I try to create it I get this: [image] I guess I will have to delete the A record with the name www.forum? If so, what about the other A record? [image] Arkshine: Then, follow the guide I will check that. Let’s see if I can follow it… What’s weird is that for example http://www.forum.alltiago.com works when Chrome is not in incognito, but stops working when it is. www.forum.alltiago.com doesn’t work on any of those. [image] Arkshine: discourse/let’s encrypt I didn’t know Discourse comes with a certificate? What would be the difference in using that vs Let’s Encrypt? As a starter on everything Discourse, I’m trying to work with what brings less complexity so I don’t get too confused. If Discourse can handle that, awesome. I would still like to understand why pick one over the other, if you don’t mind sharing? Thanks!

[image] alltiagocom: The only things with the word forum (I deleted the AAAA already): [image] alltiagocom: I guess I will have to delete the A record with the name www.forum? If so, what about the other A record? Yes, remove the one with an A record; use CNAME instead. [image] alltiagocom: I will check that. Let’s see if I can follow it… Just enter your domain in the input, then copy-paste the whole output into your app.yml config file, as I showed you in the screenshot! Be careful with the indentation! [image] alltiagocom: What’s weird is that for example http://www.forum.alltiago.com works when Chrome is not in incognito, but stops working when it is. Are you sure Chrome doesn’t automatically remove www, which you overlooked? I don’t see other explanations. [image] alltiagocom: I didn’t know Discourse comes with a certificate? No, no. Discourse uses Let’s Encrypt! Sorry for the confusion. That’s why, you should use it, it’s free and easy.

[image] Arkshine: Yes, remove the one with an A record; use CNAME instead. But both A records or just the one with the www.forum name? [image] Arkshine: Just enter your domain in the input, then copy-paste the whole output into your app.yml config file, as I showed you in the screenshot! Be careful with the indentation! [image] Like this? [image] Arkshine: Are you sure Chrome doesn’t automatically remove www, [image] [image] Arkshine: No, no. Discourse uses Let’s Encrypt! Sorry for the confusion. That’s why, you should use it, it’s free and easy. So I still need to create an account with Let’s Encrypt? I remember when I was installing Discourse, one of the optional steps at the bottom of the instructions was to install Let’s Encrypt but I haven’t yet. So maybe after all of this is done, which I believe it is now, I should check those instructions, right?

[image] alltiagocom: But both A records or just the one with the www.forum name? The one with www.forum. You want to replace A to CNAME record. www.forum → forum.alltiago.com Remember, no proxy! [image] alltiagocom: Like this? The guide is for additional domains! So, you want to add www.forum.alltiago.com instead. forum.alltiago.com is already being handled by default. Otherwise, the location and indentation seems correct. [image] alltiagocom: So I still need to create an account with Let’s Encrypt? You have nothing to do! Just add the additional domain, rebuild. Let’s encrypt will issue a certificate automatically.
