Hello,

thanks for getting in touch.

The uah.es server certificate is signed with the old SHA-1 algorithm (at
least the CAT information shows that the expected intermediate CA is the
old TERENA SSL CA). The probable cause of your issues is that Windows 10
does not consider SHA-1 server certificates and/or intermediate CAs
valid any more.

There is nothing you as an end user can do about it. Only your IT
administrator can do something: get a SHA-256 certificate, as has been
advocated numerous times on several mailing lists.

I'm cc'ing the UAH helpdesk.

Greetings,

Stefan Winter
