• How do I get debug logs?
• How to print the current applied configuration?
• Sync Error 403 Forbidden / 401 Unauthorized

Debug logs can be generated by setting the environment variable LOG_LEVEL=debug.

The current configuration can be printed by setting the environment variable PRINT_CONFIG_ONLY=true. In this mode the whole configuration is printed as yaml, after the application terminates. This can be used to check whether passwords are correctly propagated to the application.

There seems to be an authentication issue with one of your adguardhome instances (master or replicas). Please check that username and password are correct.

If you have any special characters in the password, use single quotes in docker-compose files for the password env vars.

As docker-compose uses the $ sign for variable interpolation, $ signs in passwords need to be escaped with a second $ sign.

If the password is: my$ecret it has to be used in docker-compose env var as my$$ecret
