I tried without values, not working
Expected using the default ones provided by the container as show in log:
2023-06-23 15:49:19.225366 [warn] NAME_SERVERS not defined (via -e NAME_SERVERS), defaulting to name servers defined in readme.md
EDIT:
Just tried with NAME_SERVERS=8.8.8.8,1.1.1.1, it seems to go forward better..
But I don't understand why it was not working without this line NAME_SERVERS in docker-compose, this line was never in my conf, and without it, container should use the ones provided by you and should works , no ?
