/admin attempts to redirect to an internal port

I hadn't noticed but I seem to have this issue too. Something must've changed since I last created a shortlink link on 3 Dec.

Hello @karlemilnikka and @jdaviescoates

I have been unable to reproduce this issue from a fresh @yourls installation.
Please share the following details:

• app version from dashboard app view information
• user management option (cloudron or self-managed)
• date of installation from dashboard app view information
• content of the /app/data/user/config.php via. https://paste.cloudron.io/ with redacted sensitive details

I'll check when I can. FYI /admin/ with trailing slash works fine.

I have looked into the code of @yourls, and it seems it was always /admin/ with a trailing /.
Also, the linked admin button in Cloudron links to /admin/ and not /admin.

Thanks for looking into it, @james .

The situation is the same for me as for @jdaviescoates . Everything works as intended if I enter the address with a trailing slash. The issue only occurs when I don’t include the slash.

I run two Yourls instances with the same issue. They are configured the same way.

• App version: Yourls 1.10.2
• Package version: org.yourls.cloudronapp@1.11.2
• User management option: Yourls’ own (not Cloudron)
• Date of installation: 2025-12-31
• https://paste.cloudron.io/lixuxaqedo.php

@james Just a quick update. The issue persists after upgrading to v1.11.3.

@karlemilnikka can you write to us at support@cloudron.io . We can debug what is going on. We are unable to reproduce the issue ourselves .

@james said in /admin attempts to redirect to an internal port:

/admin

@joseph surely if you just go to /admin without the trailing slash, it happens, no?

https://yourls.demo.cloudron.io/admin - just installed yourls on the demo and it happens there.

TBH I don't think it's a big deal, it had never accidentally happened to me, but does happen if I manually left the trailing slash off. But normally I jusylt start typing my yourls url in the browser and my browser history auto-completes the full correct url with the trailing slash.

I investigated this to understand why this happens. Just idle curiosity... Turns out we don't set ServerName in the vhost configs. This is required for mod_dir to work. A ServerName in the global config also gets rid of the whole server name not set warning in all our PHP apps. I pushed a change to all the packages.

For yourls, the redirect from admin to admin/ should work now.

@girish great that a small quirk/ annoyance with one app has led to a small improvement to all PHP apps on Cloudron
