SSL certificate issue when starting ArcMap

Question

I am getting following error when starting ArcMap (10.7.1)

When I click View Certificate I can see that it relates to an old enterprise installation with an expired ssl certificate. Buuut, I have this enterprise nowhere linked in my ArcGIS applications. I think I tried to connect to it some weeks ago using ArcPro... But no issues in ArcPro so far...

If I click Yes, I can work with ArcMap but I cannot connect to ArcGIS Online, also in ArcCatalog the same. I also checked in the connections in the Administrator tool but the site is also not connected there.

Any idea how I can get rid of this?

Hi Randall,

Sorry for the late reply.

If I remember correctly the invalid host was nowhere to be found but suddenly the error didn't appear any longer, no idea why. I'm mainly using ArcGIS Pro now but when I wanted to test something in ArcMap after some time it suddenly worked without problem.

Try checking this path in the registry. Does the invalid host exist there?

HKEY_CURRENT_USER\Software\ESRI\ArcGIS Online\SignIn

The dump files I found are only for ArcPro 2.4.1, the most recent one from 29th Nov. 2019.

I am sending you the link to the dump files in a private message.

Yes, I also tried to install the certificate but it doesn't make a difference.
