Plex Media Server not downloading artwork (Yes, another one...)

Here’s how I fixed TV metadata and artwork not downloading on Server 2016 Core. This fix has the twin advantages of:

  • Installing just the two required root CA certificates
  • Both certificates have long validity times (DigiCert has 14 years validity, AddTrust has 3 years validity) - so wont need replacing anytime soon

Here’s how:

  1. Download the “DigiCert Global Root CA” certificate from https://www.digicert.com/digicert-root-certificates.htm - you’ll need the cert that is valid until: 10/Nov/2031 and has a thumbprint ending in 5436
  2. Download the “AddTrust External CA Root” certificate from https://support.cloudflare.com/hc/en-us/articles/115001186052-What-intermediates-and-roots-are-Cloudflare-issued-certs-signed-against- you’ll need the cert that has a serial number of 1 and has a SHA-1 Fingerprint ending in 1868
  3. Copy both certificates to your 2016 core install, say “C:\Temp”
  4. Logon to core server and launch powershell
  5. Run: Set-Location Cert:\LocalMachine\CA
  6. Followed by: Import-Certificate C:\Temp\DigiCertGlobalRootCA.crt
  7. And Import-Certificate C:\Temp\1.crt
  8. (optional) Run dir and confirm that you see the following listed:
    A8985D3A65E5E5C4B2D7D66D40C6DD2FB19C5436 CN=DigiCert Global Root CA, OU=www.digicert.com, O=DigiCert Inc, C=US
    and
    02FAF3E291435468607857694DF5E45B68851868 CN=AddTrust External CA Root, OU=AddTrust External TTP Network, O=AddTrust…

Refresh all metadata on your Plex TV libraries and hey presto.

Works for me!
