Import via URL - invalid URL

[Qwemep]

Hello, I was wondering if someone could help me set up tandoor.

my issue is that adding a link to the Import Recipe makes the logo spin, and thinks for a second, and then outputs

Invalid URL.

The F12 console shows this

The docker logs show this

I tried deleting and reinstalling tandoor, as well as a previous version of tandoor and the feature does not work.

I installed it by installing ubuntu on my home server and then i installed CasaOS on top of it and I downloaded tandoor from casaOS app store as a docker thing.

my yaml file looks like this

I also tried doing GUNICORN_MEDIA = 1 in my environmnet variables and it still did not work.

Thank you for your help
