connection to remote IS fails with error

Hi I try to deploy project to my remote IS, which has App platform already installed. I get unfortunatelly following errors:

Project bundle generated!
Error installing project bundle in the repository! Bad credentials for user Administrator

Bad credentials for user Administrator

But normally I can connect to this remote server from my Designer!
Maybe the JMX connection which is according to Designer to port 8075 is the real reason because thee I do not remember to opened the port 8075 for JMX connection !?
What can I check?

Hi Peter,

Even i have the similar issue, were you able sort this out?
