Issues committing to Bitbucket

I have previously been able to commit changes from Katalon to Bitbucket, the error is stating that it can’t connect to the URL, we have recently moved to a two step authentication process and added SSH Keys in Bitbucket and since then I haven’t been able to push changes. Will this be the cause?

I get the following errors

org.eclipse.jgit.api.errors.TransportException git-upload-pack not permitted
