PodFetch: Some content not working when behind Traefik reverse proxy

Describe the bug

Add a podcast (it doesn’t seem to matter which modality used, ie Apple Podcasts, Podindex or my preferred, rss feed) but the icons are not displayed for some podcasts, to clarify, if they work for a podcast series, all the episodes have the thumbnail, if it doesn’t work for a podcast series, then none of the episodes have a thumbbail.

I’m installing podfetch with docker-compose, currently on v4.0.1-16173cd2 (HEAD)

    podfetch:
        image: samuel19982/podfetch:postgres
        container_name: podfetch
        networks:
            - podfetch
            - traefik
        user: 99:100
        environment:
            - POLLING_INTERVAL=${POLLING_INTERVAL}
            - SERVER_URL=${SERVER_URL}
#            - GPODDER_INTEGRATION_ENABLED=${GPODDER_INTEGRATION_ENABLED}
            - PODINDEX_API_KEY=${PODINDEX_API_KEY}
            - PODINDEX_API_SECRET=${PODINDEX_API_SECRET}
            - DATABASE_URL=${DATABASE_URL}
            - DB_CONNECTIONS=${DB_CONNECTIONS}
        volumes:
            - ${PODCASTS}:/app/podcasts
            - ${CONFIG}/podfetch:/app/db
#        ports:
#            - 8000:8000
        restart: always
        labels:
            - "traefik.enable=true"
            - "traefik.http.routers.podfetch.middlewares=authelia@file, securityHeaders@file"

    podfetch-postgres:
        image: postgres
        container_name: podfetch-postgres
        networks:
            - podfetch
        environment:
            - POSTGRES_DB=${PODFETCH_POSTGRES_DB}
            - POSTGRES_USER=${PODFETCH_POSTGRES_USER}
            - POSTGRES_PASSWORD=${PODFETCH_POSTGRES_PASSWORD}
        volumes:
            - ${CONFIG}/podfetch-postgres:/var/lib/postgresql/data
        restart: unless-stopped

My .env file

# Podfetch

POLLING_INTERVAL=60
SERVER_URL=https://podfetch.SERVER.COM
GPODDER_INTEGRATION_ENABLED=false
PODINDEX_API_KEY=MY_API_KEY
PODINDEX_API_SECRET=MY_API_SECRET
DATABASE_URL=postgresql://podfetch:password@podfetch-postgres/podfetch
DB_CONNECTIONS=10
PODFETCH_POSTGRES_DB=podfetch
PODFETCH_POSTGRES_USER=podfetch
PODFETCH_POSTGRES_PASSWORD=password

The relevant icon file is indeed present in the folder, it doesn’t matter whether the podcast episodes are renamed or not. In the example below, I’m not renaming, but it has no effect either way.

The files have the correct permissions:

root@server:/mnt/user/podcasts/LINUX Unplugged# id nobody
uid=99(nobody) gid=100(users) groups=100(users),98(nobody)

It doesn’t seem to matter whether I use Firefox or Brave and trying an incognito session doesn’t fix the issue. I’ve #ed out the podcasts down below that are unaffected.

root@server:/# docker exec -it podfetch /app/podfetch podcasts list

Nothing is in the logs that I can see either.
