I recently bought a 10 User Licence and tried to install gliffy via
https://confluence.bamberg.wienet.ads/plugins/servlet/upm
and upload the obr File (gliffy-confluence-plugin-8.4.3.opr)
Shortly after submitting and still showing a dialog "Installing gliffy..." in the background an error is show`n and "An unexpected error occured". The spinner is still active and won't finish.
Since our server is not able to access external internet ressources,
we started confluence with the following Java Startup Parameter: -Dupm.pac.disable=true.
Can this be the cause or how can i find out what the problem is?
