If you are forcing SSL for Connections applications and using Connections Plug-ins for Notes, you may get the following error when trying to upload files through the plug-in:
“A problem with the server was encountered”
To get around this you must add the following line to the “plugin_customization.ini”:
com.ibm.documents.connector.service/ENABLE_SSL=true
The “plugin_customization.ini” you need edit is located in “<notes_installation_directory>\framework\rcp\”.
