Diff giving 404 File Not Found Error

We are seeing 404 File Not Found Errors on some files (not all) on pull requests.

Note we are using IIS as a proxy server.

All other functionality seems to be working, and the error doesn't happen on all files.

There also does not seem to be a clear link i.e. new files added - it happens to existing and new files.

Hi Algebris! Which Bitbucket Server version do you have? It looks like you might be affected by the bug BSERV-10192.

Can you share a screenshot of the message so we can confirm if you're indeed facing that bug?

Best regards!

Hi, there are actually other issues as well.

1). certain files cannot be viewed in pull request. For example, the diff of some C# code cannot be viewed.

But some C# file can be viewed.

2).  Similarly, some SQL file can be viewed in pull request diff, but some others cannot, as shown below.

Can you please urgently help? We haven't had any response for 2 weeks and this is currently blocking our daily work.

Thanks in advance.

I believe this is a different error - please see screenshots.

As mentioned, we are running IIS as a proxy server infront of Bitbucket and have a DNS entry mapped from bitbucket.algebris.lan to alg-ln-bld1v:8060.

We have both JIRA and Confluence running under the same format without issue. And note, this only happens on some files and not others. The utils.cs script below has been in our master branch from the beginning.

Is there any update on this. There has been no response for 1 week?

Hey Algebris,

 

Your last screenshot seems to show that different behaviour is occurring when you access Bitbucket Server via your IIS reverse proxy, vs. when you bypass the reverse proxy and connect to Bitbucket's listening port directly.

It could be that IIS is blocking certain types of file content as "unsafe", forcing a 404. The 404 message from your last screenshot looks like it came from IIS, not from Bitbucket Server.

Can you bypass IIS and connect to Bitbucket Server directly (i.e. via  alg-ln-bld1v:8060) and test some of diffs that were previously not working?

If you find that these diffs all work correctly when you bypass IIS, you should contact your network administrator with an example of a file that was blocked and see if it contains content or patterns that IIS is blocking. I've seen cases in the past where a reverse proxy was picking up certain string matches and deeming them unsafe, and refusing to load the request for that content, causing similar errors to the ones you're seeing here.

Let me know how you go Algebris!

 

Cheers,

Dave Chevell
