Cannot access local GitLab server only while using any IDE; Terminal access, no problem

Hardware-> PC, Windows 10
We are using GitLab locally, on-prem. We have a self-signed cert, so https authentication is not used, we rely on SSH. I have uploaded my SSH key to GitLab, and when I push/pull/clone, etc from my Terminal/CMD/Powershell, etc, I have no issues. It’s only when I try to push/pull/clone, etc from any IDE. JetBrains IntelliJIDEA will not work, Microsoft Visual Studio 2019 will not work… I have tried everything I can think of, but no luck. It is a very odd situation and I cannot understand it. Setting up the IDE on my MacBookPro, everything works as expected.
