Ubuntu Server - problem with connectors

Noob here… I’m having trouble with my connectors. Running an ubuntu server for nextcloud. I have docker installed and for a few days the connector was working fine. Now, it’s not. I’ve shut down and restart the server and it didn’t fix it. I have stopped the docker and restarted them, didn’t fix it. I loaded a “Helm” connector, too. Still not working. I’ve tried about everything I can think of to make it work, but I’m not having much success. Any ideas?
