Error when clicking on Start in TestLink after installation.

[philadelphiajt]

When starting "testlink" stack, this error comes up:

"ERROR: Error starting "testlink" stack: cannot start stack: ssh not accessible" and it doesn't start.

I downloaded bitnami-testlink-1.9.20-54-r70-osx-x86_64-vm.dmg from https://bitnami.com/stack/testlink/installer
on a MacBook Air, MacOS Mojave 10.14.6

I installed TestLink, opened up TestLink and clicked Start.

Waited a couple minutes and then got the error message: "ERROR: Error starting "testlink" stack: cannot start stack: ssh not accessible" and it doesn't start.

Clicked on OK and the status circle turns from red to orange and I can't use Testlink.

I've tried uninstalling and installing it again. Same result.

Please help?
