Summary
When viewing some files in a Pull Request in Bitbucket Server or Data Center an error is displayed saying something went wrong. Clicking the Reload the page button does not solve the issue.
Environment
- Any version of Bitbucket Server or Data Center
- A reverse proxy or load balancer is deployed in front of Bitbucket Server or Data Center
Diagnosis
The error happens in different browsers and affects multiple users. Other files in the Pull Request may be accessible, while accessing others may result in a 403 Forbidden error being returned such as the one below:
Inspecting the source code of the 403 Forbidden error page may show something similar to this:
<html>
<head><title>403 Forbidden</title></head>
<body>
<center><h1>403 Forbidden</h1></center>
</body>
</html>

<!-- a padding to disable MSIE and Chrome friendly error page -->There are no entries in the <BitbucketHome>/log/atlassian-bitbucket-access.log file that would show attempts to access the page.
Cause
The reverse proxy or load balancer itself is not allowing access to the URL, potentially due to security restrictions configured in it.
These restrictions may prevent access to URLs that contain certain keywords, file extensions, special characters or patterns.
Solution
Review the log files of the reverse proxy or load balancer to identify why the request to the specific URL was denied by it, and then adjust the configuration accordingly to allow access to the URL(s) in question.
