-------------------------------------
Resolution: Information Provided
> Misleading error message while connecting to host with underscore
> -----------------------------------------------------------------
>
> Key: ARTEMIS-4654
> URL: https://issues.apache.org/jira/browse/ARTEMIS-4654
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: Configuration
> Affects Versions: 2.31.0
> Reporter: Lauri Kimmel
> Priority: Major
>
> Underscore in hostname produces unexpected error message. See details below.
> It's problematic since
> # error message is misleading
> # hostname with underscore is valid for certain setups. I.e in Docker
> compose / swarm environments.
> # underscore in hostname works for different other client libraries. Tested
> with Postgres, InfluxDB, Redis
