Summary

Bitbucket Pipeline is unable to connect to the server even after whitelisting Pipeline IPs provided on the IP addresses to allowlist in your corporate firewall

Environment

Bitbucket Cloud pipelines 

Diagnosis

The Pipeline build is unable to connect to the server completely or intermittently even after whitelisting all the mentioned pipeline IPs.

Cause

It is possible that Server has not whitelisted all the Pipeline IPs from the list.

Solution

Use curl ifconfig.me command in the Bitbucket Pipeline IP and run the Pipeline.

If the connection fails in the Pipeline build, find out which Bitbucket IP was used in the specific build and confirm if the IP was whitelisted or not on the server end. 

In the below example shown, "34.216.18.129" is the Pipelines IP address.

curl ifconfig.me
+ curl ifconfig.me
