Installing Syncthing on Pi4 with Docker/Portainer

I'm migrating my file server from Pi3 to Pi4 and need to install Syncthing.

I followed these instructions:

https://blog.crankshafttech.co…vault-with-syncthing.html

It seemed to go well, and I can see the syncthing container in Portainer but it seems to be in a permanent state of restarting.

The container log contains multiple instances of this line:

error during connect: Post http://docker:2375/v1.40/containers/create?name=syncthing: dial tcp: lookup docker on 8.8.8.8:53: no such host

Here's the list of images. I'm guessing the Unused flag is a clue?

Please can someone advise on how I can find the fault? It was so much easier on OMV4!

OK I found the problem. OMV could ping 8.8.8.8 but couldn't resolve google.com.

I was using a static IP address for OMV (as I have always done in the past). When I reinstalled OMV with a dynamic address it worked.
