Now what? Now when I start ArcMap or ArcCatalog 10.6 on my Windows 10 PC, I get multiple messages of "This page requires a secure connection which includes server authentication. The Certificate issuer for this site is untrusted or unknown. Do you wish to proceed?" Did I change something in IE on this machine to access my new installation of Portal on a LAN without a domain or cert. authority that causes this error in Desktop? Where do I find this in the Desktop docs?
Hi Paul,
I'm unsure I understand your question.
Are you connecting to Portal via ArcGIS Desktop?
Is this a new issue - did it happen before?
Are you using a CA issued certificate?
Has the certificate expired, or was it issued against a hostname that differs from the FQDN you're requesting?
Do you see similar errors in your browser when you browse to the Portal?
While it's only speculation, the only thing I can think of client side that may have changed would be if you'd previously trusted the certificate you're using, then removed that cert from your local store. You'd know if you did that though.
