Hello, Lisa!
Have a nice day!
You can use the following steps to change the password of the CA root certificate:
1. Use WinSCP to log in to the WI. In the \opt\WI\tomcat\certs directory, change the name of the old CA root certificate library from truststore_portal.jks to truststore_portal_old.jks again.
2. Import the CA root certificate again, enter the new password. After the import is successful, check whether the login is normal. If yes, delete truststore_portal_old.jks.
Hope this helps!
