Error installing Jellyseerr - Yunohost API responded with error code 502

Hey! I have found a workaround by using docker and following this guide instead: How to install apps with Docker on Yunohost (how I did it)

But I’m not going to close this thread just yet, because I am still curious as to what I should have done/what I have misconfigured and I still want to install Jellyseerr natively.
