netsh http show sslcert
This showed me two SSL Certificate bindings. One on IP:Port 0.0.0.0:443 with the correct certificate and one on IP:Port :::443 with an expired certificate. I opened CertMgr.msc for the Local Computer (see here for instructions) and searched for the invalid certificate and discovered it had expired.
To resolve the issue I did the following
netsh http delete sslcert ipport=:::443
