Allowed Hosts not recognizing IP

[ailstyn]

Description

I've built homepage from source on my debian machine, which I normally access via cloudlfare tunnel. When I run
HOMEPAGE_ALLOWED_HOSTS=192.168.0.31:3000 pnpm start
the terminal shows

` ▲ Next.js 15.2.3

• Local: http://localhost:3000
• Network: http://192.168.0.31:3000

When try to access it locally, I get a brief flash of the dashboard followed by an error, and the terminal spits out
[2025-04-06T14:46:07.651Z] error: Host validation failed for: 192.168.0.31:3000. Hint: Set the HOMEPAGE_ALLOWED_HOSTS environment variable to allow requests from this host / port.
Accessing it from localhost:3000 results in the same thing, as well as through my cloudflare domain. The tunnel is working fine, as it can access other services and shows me the error page in the browser. Is there another config file I'm missing?

Troubleshooting

None relevant to the situation

At this point the basic mechanism for this has been proven to work so I’d suspect the issue is either a different hostname than you’ve set (so the copy and pasted logs above don’t actually correlate with the exact attempt that’s failing) or that you are not setting the env properly. Both of those are easy to verify / troubleshoot (you can set the env on the shell, verify the logs etc) and we’ll see

HOMEPAGE_ALLOWED_HOSTS=192.168.0.31,url redacted:3000
mahdi@arrakis:~/homepage$ pnpm start

homepage@1.1.1 start /home/mahdi/homepage
next start

I could still be setting it incorrectly but it looks right to me. I'll try setting the variable in ~/.bashrc next and see if that changes anything.

Does it work when using *? That would help narrow down if the issue is setting the env in general or specific value(s)

[ailstyn]

It does! both the local IP and cloudflare tunnel address resolve without issue.

Gotcha. Well it’s up to you how much you want to fiddle with it, presumably the issue is just whatever you’ve been using, as long as it’s a comma-separated (no spaces) list, literally the exact values that show up in the logs (the “hint”) it really should work…

[ailstyn]

Well I got it working by copying and pasting the env variable from the site and replacing the URLs. no idea why it worked, maybe I used a character that looks the same but really isn't. All's well that ends well, thanks!
