Summary

When adding a repository in Bamboo, after submitting the changes, Bamboo will not refresh the page and will hang with an "endless spinning wheel" animation such as:

Environment

Bamboo 7, 8

Diagnosis

The browser is not receiving or is ignoring the response from the server after the POST

Cause

After submitting a new repository creation, Bamboo sends a response to the browser containing an Inline Frame element (iframe). That response is being blocked or explicitly disabled by an X-Frame-Options: DENY header injected by the Reverse Proxy or Load Balancer.

That can be confirmed after generating a HAR file and checking for the response data:

In the example below, notice that the Reverse proxy duplicates some headers and also adds an X-Frame-Options: DENY on top of Bamboo's default X-Frame-Options: SAMEORIGIN

content-encoding gzip
content-language en-US
content-type text/html;charset=UTF-8
date Fri, 24 Jun 2022 08:13:17 GMT
server nginx/1.20.1
strict-transport-security max-age=31536000
vary Accept-Encoding
x-content-type-options nosniff
x-content-type-options nosniff
x-frame-options SAMEORIGIN
x-frame-options DENY
x-seraph-loginreason OK
x-xss-protection 1; mode=block

Solution

Work with the Infrastructure team to either remove any ClickJacking protection on your Reverse Proxy/Load Balancer. Alternatively, if the X-Frame-Options header can't be removed, forcibly set it as SAMEORIGIN for the Bamboo URL.
