Cannot add or edit nodes: Mismatched action between sender and receiver

Cause

This issue is caused by the following:

  • The additional polling engines have not been updated to the same version of NPM that the main polling engine was installed.
  • An error in the orion.web log file: 

    2017-05-24 15:03:23,883 [61] (5340) WARN  SolarWinds.Orion.Web.Platform.ApiRequest - (null)  An untrusted server certificate was received from endpoint 'https://xx.xxx.xx.xx/api2/features/'. RemoteCertificateNameMismatch
    2017-05-24 15:03:26,942 [99] (5341) ERROR SolarWinds.InformationService.Contract2.InfoServiceProxy - (null)  Error closing exception. System.ServiceModel.CommunicationObjectFaultedException: The communication object, System.ServiceModel.Channels.ServiceChannel, cannot be used for communication because it is in the Faulted state.

Resolution

Upgrade the additional polling engines (APE) to the same version as the main polling engine, otherwise, it will be unsupported and will cause different issues.

For example, upgrade from NPM 12.0 to 12.1 on the APEs, if the main polling engine is already on NPM 12.1.

See Legacy Orion product installers for main poller, additional polling engine, additional web servers, and HA.
