What causes this issue?

The reason for the bad connection state was that the RFC connection
check faced an issue with the user or password of the RFC destination.
In that case the RFC destination gets the connection state 'P'. It is
helpful if you check the destination in the transaction SM59. Start with
checking the connection with button 'Test connection' or
menu->Test->connection or <(><<)>F8>. This test don?t check the user
settings. To check the validity of user and password you have to do an
authorization check. You find it in the menu->Test->authorization or <(>
<<)>F6>. In tab 'Logon/Security' you can see the settings for logon
which includes language, client, user, password. Dependend on the
different settings like Trusted Systems and Load Balancing the settings
can differ. E. g. you don?t have a password in a destination for Trusted
Systems.
