got a problem in a WFA-Workflow.
I'm using several WFA commands in a workflow to work on a single cDot-cluster.
I use a couple of Powershell-commands that work flawless (connect & execute)
and one perl-command (from Netapp - "SnapMirror initialize or update set")
which fails on connecting to the array.
I did not change anything on the Perl-configuration that comes with WFA.
WFA is latest version 126.96.36.199.1P1 Build 3511759
Server is Win2012 R2 freshly installed.
Hope somebody can help me here?

Kindly post the exact error that you are getting.
That could help in debugging.

Sure, that's the command log output:
16:26:38.985 INFO [SnapMirror initialize or update set] ### Command 'SnapMirror initialize or update set' in 'PERL' ###
16:26:44.564 INFO [SnapMirror initialize or update set] Connecting to cluster: netapp1

16:26:53.611 INFO [SnapMirror initialize or update set] ***** Workflow Execution Failed *****
Can I provide any more logs that trigger down the cause besides that?

'netapp1' might not be reachable from wfa server. Can you try to do test connectivity of 'netapp1' from GUI-->Execution-->Credentials dialog. Also, can you try to provide IP address or FQDN of the cluster to the command ?

connectivity and credentials are definetely working,
the command "Create Storage Virtual Machine" in said workflow to the same cluster using the same credentials does work:
16:25:27.325 INFO [Create and configure Storage Virtual Machine] ### Command 'Create and configure Storage Virtual Machine' in 'POWER_SHELL' ###
16:25:36.091 INFO [Create and configure Storage Virtual Machine] Get-WfaCredentials -Host netapp1

16:25:36.185 INFO [Create and configure Storage Virtual Machine] Connect-Controller -Type CLUSTER -Name netapp1 -Credential System.Management.Automation.PSCredential -Vserver -Timeout 60000
16:25:36.263 INFO [Create and configure Storage Virtual Machine] Connect-NcController (with credentials) -Name netapp1 -Timeout 60000 -ErrorAction Stop
16:25:43.435 INFO [Create and configure Storage Virtual Machine] Connected to cluster node

16:25:50.655 INFO [Create and configure Storage Virtual Machine] Command completed, took 23330 milliseconds
--> only difference in that workflow is that the command that is not working is written in perl. All others (written in powershell) do work absolutely fine.

Test-Connectivity uses powershell to verify connectivity. So this result was expected. To debug perl, can you do the following.
my $wfa_util = WFAUtil->new();
$wfa_util->sendLog('INFO', 'Connecting to cluster: ' . $Cluster);
my $server = $wfa_util->connect($Cluster);
How does this work for you?

sry for long delay.
Tried it, exactly the same problem:
11:12:03.032 INFO [test_connectivity] Connecting to cluster: netapp1
11:12:03.079 INFO [test_connectivity] Credentials successfully provided for 'netapp1'
11:12:04.188 INFO [test_connectivity] Trying to connect to netapp1 using HTTPS
11:12:12.220 INFO [test_connectivity] Trying to connect to netapp1 using HTTP
11:12:15.111 ERROR [test_connectivity] Failed executing command. Exception:
Unable to connect to array
--> Also installed a fresh WFA on a Win2012R2 Server, same result
--> Maybe some problem on securing the connection?

There is a known problem with Perl NMSDK. If host names are unable to be resolved by the DNS, this problem is seen.
I suggest you add the hostname netapp1 in your WFA's windows's hosts file.
Got to: C:\Windows\System32\drivers\etc and open the file hosts for editing using some text editor like Notepad++
Add a line like
<IP_Address_of_netapp1> <FQDN_of_netapp1> netapp1
Now back to WFA and try the same test command.
