You receive the error when synchronizing with the SolarWinds Update Catalog:

Unexpected website connection issue when trying to download '': The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.


All Patch Manager versions


There are certificates that are not being installed in the Trusted Root CA store on the Patch Manager server.

Resolution 1:

  1. Go to the SolarWinds website using a browser within the Patch Manager server or a workstation.
  2. Manually install the certificates across to the server.
  3. Install the certificates in the the Trusted store:
    a. Install the certs in the Trusted Root CA.
        Note: The certs might get immediately removed by a GPO or antivirus.
    b. Place them in your GPO to be installed.
    c. Install them manually.

Resolution 2:
