password. Some target systems such as ABAP system will send in this
error case an HTML error page containing some hints about problem
details.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Check the error context to see which authentication level and method are
configured for the specified logical port and ask the administrators of
the target system for help.

"Short Text" to see the whole HTML error page.
