The first instance I created stopped updating and refused to work with simple methods suggested on the net.

I created a whole new instance on the second day and deleted the persistent dir so I have no data to work with for troubleshooting.

The probable cause where the YouTube RSS feeds that seem to be producing errors like 404 and 500.

• I will set up a second instance with the YouTube links only to find out if that was the culprit.

• The URL I had to use on newsboat was http://freshrss.lan:8080/api/greader.php
• The URL for FocusReader is https://rss.lan:8443/api/greader.php using the API pass

• The www.linuxserver.io guys expose the configs and logs on the host mapped folder under config..

• The Github page of the docker image is at https://github.com/linuxserver/docker-freshrss

docker volume inspect freshrss-data sudo ls /var/lib/docker/volumes/freshrss-data/_data/

docker logs -f freshrss

docker exec -it freshrss sh
