How to check the connectivity to your backend system in Business Application Studio

Dear Andre,

thank you for the great blog! we do get the 404 error! but it is not because of the wrong password! we connect BAS with our Bitbucket through cloud connector. on the Cloud connector directly, we can curl to our on premise bitbucket. But on the BAS when we curl our on premise bitbucket the error 404 not found pops up. could you maybe take a look at the output attached? Thank you & BR

user: user $ curl -v -i GET https://its.company.com/bitbucket/scm/sap/x.git -u USER
