Can't install Gliffy

I recently bought a 10 User Licence and tried to install gliffy via

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?

You might be able to find the the error in the Confluence logs if you can access them. 

A common issue is the plugin size (limited to 32 MB), which can be resolved by increasing the packet size to a higher number (gliffy is around 76 MB)

Hope it helps

this could indeed be the problem. I changed therefore maxAllowedContentLength in web.config (IIS) 

<requestLimits maxAllowedContentLength="2147483648" />


After i restarted IIS, any requests produced a "500 - internal server error". Then i removed the new config parameter and tried again. Still a 500 internal error.

This are the errors a see in the logfiles:

Do you have any ideas what the problem could be?

Hello, I imagine you are affected by this known issue: according to the logs.

You can use the workaround to disable it: 

Disable the "scheduledjob.desc.LaasPerformanceLoggingJob" from Settings/Cog > General Configuration > Scheduled jobs



i just realized that the root cause of my problem was i wrong syntax in web.config. 

Now, with the increased UploadLimit everything works.

Thanks for your help!
