In my case the reason was since the remote repo artifact (non-central) had dependencies from the Maven Central in the .pom file, and the older version of mvn (older than 3.6.0) was used. So, it tried to check the Maven Central artifacts mentioned in the remote repo's .pom for the specific artifact I've added to my dependencies and faced the Maven Central http access issue behind the scenes (I believe the same as described there: Maven dependencies are failing with a 501 error - that is about using https access to Maven Central by default and prohibiting the http access).

Using more recent Maven (from 3.1 to 3.6.0) made it use https to check Maven Central repo dependencies mentioned in the .pom files of the remote repositories and I no longer face the issue.
