Part of the Apex Centrall installation process is to log in to the SQL server, and create a table to save the Apex Central data. However, the installation will not continue if the login/authentication to the SQL server fails.
The authentication to the SQL server can fail because of an incorrect password, or if the password contains an unsupported special character.
To resolve the issue, make sure that:
- The password is correct.
- The password should not have the following characters:
- Ampersand (&)
- Greater than (>)
- Less than (<)
- Caret (^)
- Semi-colon (;)
- Comma (,)
- Pipe or Vertical Bar (|)
