Since upgrading to Bitbucket Server 6.4 from 4.5, I can't get to the Atlassian Marketplace. When I click on Manage Apps in the Admin Window, it attempts to connect to the Marketplace but fails. I have entered the proxy information that was used for Confluence and the old (4.5) version of Bitbucket into the bitbucket.properties file and restarted the Bitbucket service (Windows Server 2016), but to no avail. Any assistance would be greatly appreciated.
