After 5 days of trying and head banging I've given up.
Following issue: - Company network - Windows 10 machine - Joined to the domain - trying to access a Cisco Call Manager portal which is hosted internally and accessible via HTTPS only
Since about 2 weeks I'm no longer able to access the website via IE - I'll get: error message
In Chrome everything works fine, even though it throws a certificate warning at me, which I just skip:
Your connection is not private
Attackers might be trying to steal your information from ''website'' (for example, passwords, messages, or credit cards). NET::ERR_CERT_AUTHORITY_INVALID
Now the thing is that I need to have the IE working with this site, because we have a 3rd party tool which uses IE to get some data off the website. All other internal HTTPS sites work, external sites work as well. I have tried to login locally and no luck either. Colleagues can access the page without any issue.
I even did a clean(!!) install and it worked in the beginning. Joined the domain and next thing I tried it didn't work. Has somebody any kind of hint or clue? I don't understand this world any longer.
Thanks for any input!
so interestingly I get to the page if I do the following int IE11: Advanced; Security; tick only "USE SSL 3.0" or if I have "SSL 3.0" "TLS 1.1" "TLS 1.2" ticked. If I tick TLS 1.0 it errors out. If I tick SSL 2.0 it errors out as well.
What could this be that I can reach the page before I join the domain? Or how come that other team colleagues can get to the page with the exact same settings? (which is by default all SSL unticked and all TLS ticked.
