I have two Unraid servers and used to use Portainer. I had it setup for one instance of Portainer to be able to manage both servers. I had added this line to the docker.cfg to allow docker to be managed remotely.
I removed this line and it appears to be working now. Not sure why this decided to be a problem now. I stopped using Portainer awhile ago and have rebooted unraid since then. 🤷♂️
