DellWMS-ConfigurationUI-Package cannot be installed

Hello,

I keep having the problem that I can not install newer ConfigurationUI packages in the Admin Konsle. It loads for a while and then at some point a timeout appears. Then when I try again to upload the ConfigurationUI package I get the attached error message. Only when I restart the entire server can I make another attempt, but with the same result.

What can I do to be able to install the package successfully?

WMS version 4.1
ConfigurationUI package 1.9.986

Thanks in advance.

P.
