"no managed servers found" via HMC rest api after xormon installation

Hi guys!

So I'm running all lpar2rrd/stor2rrd and now Xormon on one machine (Ubuntu).
HMC rest api fetches worked fine until I installed Xormon (xormon also working fine).
When I do the connection check, result is that API works, but no managed servers are found, and no data is collected. But they are definitely there. If I switch the same HMC to "HMC CLI (SSH)" option, all data is collected as normal, so data is also there.

Any advice where to look at?

API host network connection: TCP connection to hmc-XXXXX:12443 is OK.
API authorization (lpar2rrd): OK

API data test
no managed servers found

Here is the last output in the logfiles (HMC name changed due to security reasons):

    Hi,
    it looks like it tries to comunicate via http (https is needed).

    . etc/lpar2rrd.cfg ; $PERL bin/hmc-restapi-test.pl your_hmc_ip "DEBUG_BAD_HMC" | grep -vi pass > o.txt;

    Send us the output of the command above via https://upload.lpar2rrd.com
    Note a short description or link to this thread in the form. Thanks.

    Update: 
    After quick analysis from Xorux it came to light that I missed out the update of the VMWare Perl SDK on my ubuntu machine. (See here: https://www.lpar2rrd.com/https.php#VMware)
    After that step, it works. Thank you guys!

    Have a nice day
    BR
