Setup with docker-compose and Cloudflare Tunnel

[clemone210]

Hello!

I've tried to setup the project with Cloudflare Tunnel, but I cannot seem to get it working.

The server is setup with docker-compose. I changed the secret in the config.php.

Cloudflare Tunnel is setup to point my subdomain.domain to the docker container at the specified port.

On the client, i've setup the secret and the URL.
When running I get the following error:
Error: Failed to upload screenshot. Server returned status code '500'.

On the server it shows this error:

Any tips to resolve it?
