Teslamate: Login Fails via webinterface

[Highlander1694]

Login Fails via web interface on port 3000

New install just now. All 4 docker containers running

• database starts ok, no error
  -mosquito starts ok, not errors
• grafana starts ok, no errors web browser shows grafana interface
• teslamate starts, webbrowser shows login interface, login with correct credentions results in "Error: unknown" on web interface

See teslamate console log below.

Expected behavior
Well it is supposed to get an API token and say something positive I suppose :)

How to reproduce it (as minimally and precisely as possible):
Restarted containers, try again, same result.

Found out that the docker is not resolving DNS. Login on the docker container shows DNS resolution finds no valid servers.

Problem seems to be related to this: https://github.com/pi-hole/docker-pi-hole/issues/455

[Highlander1694]

Found the solution. QNAP Docker (for some reason) makes a /etc/resolv.conf with a DNS resolver of 127.0.0.11. That should be 127.0.0.1, not 11...

Solution. Delete the Docker containers. Redo the containers with the change below.

Add the following lines before the "environment:" and make sure the "cap_add" and "dns:" are aligned with the "environment:" (same distance from left margin)
cap_add:
- NET_ADMIN
dns:
- 127.0.0.1
- 1.1.1.1

I am a Docker newb, I found the hint for the solution here https://github.com/pi-hole/docker-pi-hole/issues/410

Wow Highlander1694. Your info saved me from a big headache. Fix works.

Instead of deleteing docker, I edited the YAML information and added the information you provided. There is an edit button in the ContainerStation Overview near the end of the listing. The container restarted itself upon saving and fixed the issue.
