Unable to login to DB config page in Talend Administration Center

[TalendSolutionExpert]

Problem description

Cannot login to the DB config page in Talend Administration Center.

Solution

Try using the default password on the DB config page > admin.

If that doesn't work, navigate to the Configuration.properties file (<Talend_Installation>\tac\apache-tomcat\webapps\org.talend.administrator\WEB-INF\classes) and in that:

# Password to access to DB config page in the web-app:
database.config.password=

To do this, perform the following steps:

1. Stop Talend Administration Center.

2. Go to the Configuration.properties file > database.config.password=.

3. Replace the encrypted password with a password in plain text.

4. Save the file.

5. Restart Talend Administration Center.

6. Try to use that new password you set for the DB config page login.

I know the password.  The issue is after I input the password. Get the error message.  It is not password wrong.  Should I remove master key after using plain text for database information ?
