Troubleshooting Connection Reset By Peer Errors When Using BitBucket

Problem

When attempting to use BitBucket Server as a VCS, a connection reset by peer error is present. This error includes the IP address of the BB server and a port number. 

Prerequisites (if applicable)

• Bitbucket Server

Cause

• The issue may be due to erroneously configured settings, or a transient networking error. 

Overview of possible solutions (if applicable)

Solutions:

• If encountering this error when attempting to complete a run on a workspace, try editing the VCS settings to change the repo to something else, then back to the desired one

• Review the networking requirements found here

  • Note that Bitbucket Data Center's default ports are 7999 for SSH and 7990 for HTTP. Check your configuration to confirm your BitBucket instance's currently-configured ports.

• Discuss the error message with your networking teams, providing them the full error message and timestamps for their investigation.

Outcome

Once the connection issues are identified and resolved, runs should progress as expected. If they do not, please reach out to Hashicorp Support for more assistance.
