git clone works in ide but not git bash CLI

[David Brown]

Howdy, I have a conundrum:

App: Spring Cloud Config Server
envvars: GIT_URL and SSH_KEY
IDE: Intellij 2018.2.4 Ultimate

When I use the IDE to assign the SSH_KEY value all is copacetic.

If I assign the envvar at the Git Bash CLI:

com.jcraft.jsch.JSchException: Auth fail

Any guesses?

Thanks and regards,
