====== Docker - Arr - Gluetun - Troubleshooting - DNS over TLS not working? [dns] using plaintext DNS at address 1.1.1.1 ======

====== What is the problem? ======

<code bash>
docker logs gluetun
</code>

returns:

<code>
...
[dns] using plaintext DNS at address 1.1.1.1
...
</code>


When using the DOT functionality, the logs say **[dns] using plaintext DNS at address 1.1.1.1**.

  * Is this just a misleading log statement?
  * Is it failing to use DNS over TLS and falling back to plaintext?

----

====== Solution ======

Despite the fallback DNS message, from the container it could not resolve that address, but explicitly setting

<code>
DNS_ADDRESS=1.1.1.1
DOT=off
</code>

Fixed my issue.
