TLS and Basic Auth not working together

[brockolicheese]

I have enabled both Basic Auth and TLS and I am able to get them to work standalone, but neither are able to work when both are enabled. Is this an issue with running a self-signed cert?

mailrise.conf:
configs:
proxmox:
urls:
- discord:///*******************

tls:
mode: starttls
certfile: /etc/ssl/certificate.pem
keyfile: /etc/ssl/privatekey.pem

smtp:
auth:
basic:
username: password
test: Test123456

Docker Compose YAML:
services:
mailrise:
image: yoryan/mailrise:latest
container_name: mailrise
ports:
- '8025:8025'
restart: unless-stopped
volumes:
- ./mailrise.conf:/etc/mailrise.conf:ro
- ./certs/certificate.pem:/etc/ssl/certificate.pem
- ./certs/privatekey.pem:/etc/ssl/privatekey.pem

I am wondering if anyone else has had this issue or if it is fixable.

Thanks
