Upgraded to 2018.3.6f1 and Unity Package Manager won't work

I work for a large company which depends on Unity for our VR development. I upgraded to version 2018.3.6f1 today and started a new default project to run tests on. Before even play/debugging, I get the following errors in the console:

Cannot perform upm operation: self signed certificate in certificate chain [NotFound] UnityEditor.EditorApplication:Internal_CallUpdateFunctions()* Error searching packages online. UnityEditor.EditorApplication:Internal_CallUpdateFunctions()

We are required to use a corporate proxy and have always set this up as follows:

HTTP_PROXY=http://our-proxy.our-domain.com:80

HTTPS_PROXY=http://our-proxy.our-domain.com:80

NO_PROXY=localhost,127.0.0.1

UNITY_NOPROXY=localhost,127.0.0.1

These settings are still allowing licence checking and Asset Store connections but obviously our network controls are blocking the UPM.

I've read all the existing forum threads and have tried everything I can think of but nothing works. I've tried testing the UPM server at http://127.0.0.1:10010/health and I get the normal OK JSON response. Please advise so we don't have to re-install the older version 2018.2.x

Thanks, Tom
