[ProGet] Invalid URI when accessing feed

[pariv_0352]

I run proget behind reverse-proxy. And that proxy sits on non-standard port.
And all works fine, but when I'm trying to access feed through browser it fails with Server Error 500: Invalid URI: The hostname could not be parsed.

If I run proget on non-standard port without reverse-proxy feed access works.
Looks like when proxy sets header X-Forwarded-Host to something with explicit port, it fails.
e.g. www.testdomain.com:82.

I found out that X-Forwarded-Host header is not very well defined in the case of ports. But I think proget shouldn't throw exceptions in this scenario and show feed page.

There is a workaround to set Web.BaseUrl, but its not suitable for me, because port may change over time. And I dont want to change Web.BaseUrl every time it changes.

Hi @pariv_0352,

What version of ProGet are you using?

Perhaps this is related to this:

I use Version 2023.9. And yes, I saw that thread, but looks like it is a bit different.

Hi @pariv_0352,

Thanks for clarifying; looking closer, ProGet requires that X-Forwarded-Host is simply a hostname. You're right, there is no "standard" for this, but that's what ProGet does for the time being.. and if the input is invalid, then you get the error you'll see.

I would change your reverse-proxy header configuration to:

• X-Forwarded-Host: www.testdomain.com
• X-Forwarded-Port: 82

Hope that helps,
Steve
