Source Tree: "This is not a valid source path/URL"

[Joe Pigott]

I have created a repository on Bitbucket, and I clicked the Clone in SourceTree button. It comes up with the address 'https://*********@bitbucket.org/*********/horizons-edge.git' This address was created by Bitbucket, but it doesn't seem to connect in SourceTree and comes up with the error "This is not a valid source path/URL" Can anyone help me solve this?

EDIT:

As the problem stated, you have SSL certification issue. Try searching the Atlassian KB docs, there will be something written about it for sure, like this one: https://confluence.atlassian.com/display/SOURCETREEKB/Resolving+SSL+Self-Signed+Certificate+Errors
