Password Manager Service is unavailable (4267249)

When initializing or reinitializing a Standalone or DMZ server the following error is reported even though the correct port and the correct certificate are used on both the Standalone server and the PMAdmin site.

And in the ‘PM – One Identity Password Manager’ event log the following error is reported.

“System.NullReferenceException: Object reference not set to an instance of an object.”

OR

"Please provide the appropriate data. Your connection was interrupted."

CAUSE 1
This can be caused by a port conflict most commonly seen on Port 8081 when McAffee Anti Virus Software is installed on one of the servers.

CAUSE 2
A network appliance is shaping or interrupting traffic.

1. Change the port on both the Admin & Standalone servers. (to port 8085 for example)
2. Reinitialize the Standalone server.

Note: It may be necessary to open up the new port in the firewall on both servers.

RESOLUTION 2
Review logging on any network appliances and remove any rules which are shaping or interrupting network traffic on the configured port.
