I have a case where end users can use their browsers to connect to Identity Governance Portal on port 8080. However, when the same user tries to connect on port 443, they get a page not found error.
Chrome: No users have any issues using https
Firefox: No users have any issues using https
IE 11: Some systems are able to connect using https and others are not. For example, a user cannot connect using https from their desktop, but have no problem when using a virtual desktop. The IE settings seem to be the same in both cases.
IG is using JBoss 5.1 and I suspect that maybe somehow they have locked IE 11 down so that it refuses to negotiate a connection using TLS 1.1. Upgrading JBoss is not an option right now.
I did find that it is possible to specify the minimum TLS version with a register key, but this key is not set on end user machines that are having issues. Unfortunately, all of the systems that I have access to do not experience the issue, so it makes it hard for me to troubleshoot.
Any ideas for how to troubleshoot this?
