Can't upload packages larger than 20MB

When attempting to upload a 60MB package through the UI we see the following error: "There was a problem with your request. Unhandled error when communicating with the Octopus Deploy server. The server returned a status of: 404".

Large files published directly from VSTS are fine and so are files smaller than 20MB. We can get around the problem by uploading a smaller file and then replacing it directly on the server with the larger file but this is far from ideal!

We have just upgraded to v4.1.7 and still having the issue.

    Hi Adam,

    Thanks for getting in touch! Octopus support packages of a much larger size than you have here. The 404 error you are seeing means that the package is most likely not making it to where Octopus is looking. We have seen in the past that IIS Proxy servers have blocked files over a certain size. The following blog post I found seems to cover this, including the 404 you are seeing.

    Let me know if the above helps or if this is not the case. :)

    Best regards,
