The database password has a # in the beginning of the password such as #PassWord123! . To avoid this issue, do not use a "#" at the beginning of the password. This is the location where the initial password is set.
Reset the Redis database through the command-line interface on the VSI virtual machine. Log in to the VSI Virtual Machine. This can be done through VMware by launching a virtual console, or SSH to the VSI VM. If the VM has never been logged into previously, the username and password is root . A password change is required after login. Run the following command to reset the Redis password: root@photon [ ~ ]# /opt/files/iapi-maintenance-util/apis/redis/redis-config.sh --rollback WARNING: The DOCKERHOST variable is not set.

There is an alert at the top of the window to reset the Redis password. Set a Redis password that does not have "# or !" At the start of the password, after the password is set, the screen can take up to 5 minutes to refresh.
