Authentication failed using instance:connect in Apache Karaf 3.0.2 - apache-karaf

Question

Can someone please help me why this call is no longer working in Apache Karaf 3.0.2. I verified that it was working in version 3.0.1. All instances are up and running, but I am unable to connect to one of my instances directly from the command line.
su - karaf -c " client -h localhost -a 8101 -u karaf -r 50 -d 2 \" instance:connect -u karaf -p karaf test1 \\\" feature:repo-list \\\" \" "
Logging in as karaf

The call is part of an automated process and I cannot connect to a specific instance directly. Is there any specific configuration required, that was not necessary in 3.0.1?
UPDATE #1:
I have added the verbose option... Does it give you any hints what to do?

I switched the logger to DEBUG and I found this exception:
