Why can't I connect to THWACK from NPM ?

Your SolarWinds Platform server must be able to open internet connections to connect to THWACK.

If the connection is blocked by a firewall or a proxy:

  • The list of shared pollers cannot be retrieved from THWACK
  • Any operation that relies on communication with THWACK, such as the upload or download of a poller, will fail.

Check your firewall and proxy settings to make sure that your SolarWinds Platform server can connect to the internet.
