Let's give it a try...
The Jenkins job config is stored in Jenkins, not in git, correct? Do you know how I could have a look without Jenkins credentials?

Thanks!

The whole pipeline is defined in this Jenkinsfile. There isn't that much in the Jenkins job itself except for defining the parameters and some default values.

I already tried adding some connection related parameters to MAVEN_EXTRA_OPTS but it didn't help much so far.
E.g. parameters like:

-Dhttp.keepAlive=false
-Dmaven.wagon.http.pool=false
-Dmaven.wagon.http.retryHandler.count=3
-Daether.connector.http.retryHandler.count=5
-Daether.connector.http.reuseConnections=false
-Daether.connector.http.connectionMaxTtl=25
-Daether.connector.connectTimeout=120000

Reverting Maven and Java to some older versions to see if it is due to a recent regression also didn't help.

Next I might want to try if the pipeline has the same connection issues when it runs on agent1 instead of the built-in node.
