Updated Sinema Remote Connect Client from 3.0.1 to 3.2.0.1 stuck on connecting

Updated Remote Connect Client from version 3.0.1 to version 3.2.0.1 - server had been updated to 3.2 and requested an update in the client.

My devices show online, but I am unable to connect - connection show "STARTING", with "Establishing VPN tunnel..." message at the bottom of the window.

I downloaded the update from here: https://support.industry.siemens.com/cs/cr/en/view/109954687

(The 453.4MB one)

The settings populated the new version automatically. Is there something I am missing in the setup of the new version?
