The Atlassian Community can help you and your team get more value out of Atlassian products and practices.
we recently build Bitbucket datacenter and Bamboo servers
- we are trying to integrate both, getting "We couldn't connect to Bitbucket, possibly because that instance is behind a misconfigured proxy"
Welcome to the Community!
When you buld these servers are you using your own hosted infrastructure or are you using a cloud provider (AWS, Azure, etc.)?
Are you able to establish a connection between the machines outside of the Atlassian applications (using ping or something to that nature?)
Have you checked the log files for either BitBucket or Bamboo to see if there is any additional information provided on the errors when you are trying to connect?
You can find the logs in these locations:
I hope that helps get to the source of your issue.
