Unable to reload Maven project: Cannot reconnect. java.lang.RuntimeException: Cannot reconnect

i got a new Mac Book and installed IntellJ, as soon as I try to import (new Project from existing source) a maven project i get the error “Unable to reload Maven project”. To make it simpler, i just created a new simple maven project via start.spring.io to make sure I dont have any fancy dependencies.

I also tried to run mvn install via terminal. This was working out!

I know this issue was posted several times, but i already tried all the suggested things.

I made sure that my hosts file only contains 127.0.0.1 localhost. Also checked via

# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.

ping localhost​

and cache refresh that localhost really gets converted into 127.0.0.1

furthermore i updated maven to version 3.6.3 and and JDK to 1.8.0_251. I ran mvn install via terminal exactly with these versions of maven and JDK and it worked out pretty fine.

I also checked the firewall, i could not see any blocked call (anyways on terminal it was working).

some more configs:
maven version

maven jdk importer

java versions

intelliJ version
Here i also changed the version from 11.0.7 to 1.8.0_251 (via Choose Runtime Plugin) with same result.

Many thanks in advance! best D.

ESET network protection is known to block localhost connections which is causing RMI to fail with this error:

ution.rmi.RemoteProcessSupport - java.rmi.NotBoundException: _DEAD_HAND_
ution.rmi.RemoteProcessSupport - at sun.rmi.registry.RegistryImpl.lookup(RegistryImpl.java:227)
ution.rmi.RemoteProcessSupport - at com.intellij.execution.rmi.RemoteServer.start(RemoteServer.java:93)

Disable ESET or adjust the netwrok protection rules. Contact ESET support for more details or the configuration changes you need to make to allow localhost connections to work.
