NCM not working in 2020.2.5

After upgrading to 2020.2.5 everything related to NCM has stopped working.  Configs aren't downloaded anymore, RTN stopped functioning, trying to view anything related to NCM on the website ends up with a timeout error.  This just started after the upgrade.

I've tried re-installing NCM, re-running the configuration, rebooting all the servers and nothing helps.  The one interesting thing is an error that started showing up in the NCMBusinessLayerPlugin.log file after the upgrade:

2021-03-31 11:34:46,760 [8] ERROR SolarWinds.Orion.ServiceDirectory.Wcf.ServiceDirectoryAttribute - Service Directory could not register the service 'NCM.BusinessLayer'.System.AggregateException: One or more errors occurred. ---> System.InvalidOperationException: Endpoint with a name 'NcmNetTcpBinding' not found in a service 'NcmServiceEngine'.

Is anyone experiencing something similar?  I opened a support case about 6 hours ago but it's still at the 'not started' stage.

  • Multiple times.  One of my coworkers found an article about config files not being updated properly in an NPM upgrade so we took a shot and followed the same procedure for NCM.  We renamed \Program Files (x86)\SolarWinds\Orion\NCM\SolarWinds.NCM.BusinessLayerPlugin.dll.config and re-ran the installer and configuration.  Everything started working again after that.
