Docker Error response :Address already in use

We are running a test setup of unRAID with MariaDB, Nextcloud, and Portainer as containers.  We have been working with 6.3.5 with good success but I wanted to test out the features of 6.4.rc17b so I could see setting up containers with different IP addresses for our environment.  I upgraded and rebooted unRAID and when I clicked on the Docker tab it showed my 3 containers with updates on each of them.  I updated MariaDB and Nextcloud but Nextcloud will no longer start. 

I rebooted the unRAID server.

Stopped other containers.

Reinstalled Nextcloud.

Removed and reinstalled Nextcloud.


upon the reinstallation I get this following error...


root@localhost:# /usr/local/emhttp/plugins/dynamix.docker.manager/scripts/docker run -d --name="nextcloud" --net="br0" --ip="" -e TZ="America/Chicago" -e HOST_OS="unRAID" -e "TCP_PORT_443"="443" -e "PUID"="99" -e "PGID"="100" -v "/mnt/user/appdata/nextcloud2/":"/data":rw -v "/mnt/user/appdata/nextcloud":"/config":rw linuxserver/nextcloud

/usr/bin/docker: Error response from daemon: Address already in use.
The command failed.

Previous to this error message when I would try to just START the Nextcloud container I would receive a different error...


time="2017-12-19T14:30:25.920387364-06:00" level=error msg="Handler for POST /containers/7de70fb44468/start returned error: driver failed programming external connectivity on endpoint nextcloud (cee2b3880623720d10777ca025b3a6d26fb7e4c415137f6195e7e17c14d0866f): Error starting userland proxy: listen tcp bind: address already in use"


Seeing that it stated the "address already in use" I attempted to assign a static IP thinking that was the hiccup but the static IP didn't change anything.


We are getting ready to build a production server for unRAID and Nextcloud.  I could just wipe my current test and start over again but the bottom line is that I really want to get some more familiarity with unRAID and troubleshoot issues before we move into production in 2018.  Anyone have some wisdom on where I should start to troubleshoot this?  We have zero critical data in this environment at all so I am free to try anything to troubleshoot it.


I have attached Diagnostics in case they could shed in light on the issue.

It's probably because the Unraid webui can be served over 443 now, have you enabled that?

That would stop Nextcloud from working.
