Validate the connection

Cause 1:

User and password are incorrect.

Cause 2:

The connection contains real-time replication, in this case the password is not updated in remote source. It gets updated only when connection is paused.

Solution 1:

Verify the user and password.

Solution 2:

1. First pause the Real-Time Replication Status
   
2. Then edit the connection, input user and password.
3. Save and validate the connection.
4. Re-start the Real-Time Replication.
