Thanks for opening your first issue here! Be sure to follow the relevant issue templates, or risk having this issue marked as invalid.

[ghinks]

I'm sure I am not configuring something correctly but if not then I'm happy to raise a PR to the docs so that others do not make the same mistake.

[j0nnymoe]

Are you setting an app URL?
Is this a fresh or existing install?

[ghinks]

Thank you @j0nnymoe this indeed a fast response. I did try it using

- APP_URL=http://192.168.7.147:8080

with the same result

[j0nnymoe]

Are you re-creating/deploying the container when you make this change? Also you should be replacing the /path/to part of the /config volume as it's a placeholder.

[thespad]

Check the application log at /config/log/laravel.log for the specifics of the 500 error.

[ghinks]

I am not re-creating , the laravel.log is empty.
I will try re-creating.

[j0nnymoe]

Just a note, when using compose, if you change your compose file, you need to down then up -d to recreate

[ghinks]

noted. Yes I have been deleting the last image and checking with docker ps -a each time. No luck so far. This is the current config I am using

I can see the nginx logs are 192.168.7.147 - - [18/Apr/2026:13:45:04 +0000] "GET / HTTP/1.1" 500 6431 "-" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/147.0.0.0 Safari/537.36" 192.168.7.147 - - [18/Apr/2026:13:45:04 +0000] "GET /fonts/inter/inter.css HTTP/1.1" 404 6672 "http://192.168.7.147:8080/" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/147.0.0.0 Safari/537.36"

So I am hitting the container and I get the error image in the browser.

[ghinks]

Sincere thanks for the help Jonny Moe.

[j0nnymoe]

Are you providing a valid app key?

Need to see laravel logs

[ghinks]

Yes, I used a valid key , but there are no logs being generated in the laravel log file at all. I will re-check shortly and provide more information.

[j0nnymoe]

Just deployed this again myself due to moving my instance, unable to replicate.
