TLS Error in IE or Edge when redirecting from "On-Demand Cert Auth" to Logon Page

I'm getting an error from IE based browsers IE or Edge when falling back from and "On-demand Cert Auth" to a logon page. I get the "Can't connect securely" "checkTLSError from the browser.

 

A refresh action in the browser brings up the subsequent logon page. I don't have any issues with Firefox or Chrome, but the IE browsers are the most used as this is a large sharepoint farm and the logon pages are used for users who are token-exempt.

 

I'm assuming this is a client side error produces by GPO or other deskside hardening of the domain workstations, but wondering if there is any remediation I could do on the F5 to refresh the page between the fallback action and the logon page to take the burden off the user and to hide the IE error from them.

  • Figured it out - it was a portion of an x509v3 cert parse irule that was causing this condition. Reverting to an older version resolved the issue. Not sure of the specific event or cause that was impacting the 302 redirects. I haven't debugged that far into it.
