ProGet update checker gives error (error 411)

[g.j.spoelstra_9664]

The update checker was working in our Proget enviroment for a while today we get this:

INFO: Checking for updates from inedo.com...ERROR: Error checking for updates: System.Net.WebException: The remote server returned an error: (411) Length Required.

What could this be?

Product: ProGet
Version: 5.1.4

It may have been a temporary outage, or a proxy problem, or something. You can ignore it. If you restart the service it will probably go away.

We still have this issue.. restart of the service does not fix the problem.

First, make sure that the IntegrationUrl property (Advanced Settings) is set to https://inedo.com/pg.

Assuming that it is, then if you're continuing too get the problem, then it means there is a network problem between your ProGet server and Inedo.com. Maybe it's a firewall, proxy server, or something like that.

You may want to check with your network/operations team about this, as they can probably trace/see what's happening between the two

https://inedo.com/pg/ was set in the advanced settings, ihave changed it to https://inedo.com/pg/update. After a restart from the service, the problem still occurs.
I will ask the network deparpment.

Sorry, I made a mistake.

Please make sure the setting is https://inedo.com/pg/.

If you visit https://inedo.com/pg/update in your browser, you can see the XML that ProGet will otherwise see.

The strange thing is when i access the url with an internet browser on the machine where proget is installed i get a nice XML.

<?xml version="1.0" encoding="UTF-8"?>
<proget currentVersion="5.1.5"/>

So i think it is a ProGet issue.

ProGet access that URL differently than a web browser, and typically under a different user and proxy context. But I can say that we have thousands of ProGet installations successfully accessing that without receiving 411 errors.

So, this means there is a network problem between your ProGet server and Inedo.com.

Your network folks have tools, like Wireshark, and can diagnose what's happening between.

Ok i will get back on this after i checked with our network department.

Dear Alana,

I think your organisation should take problems of your users more seriously, because this issue has been open for two months. You said it was a problem on our side... but now i see in the releasenote from proget 5.1.11 it was a problem on your side.

https://inedo.com/proget/versions#v5.1

It is fixed now.

We take problems very seriously, but we need to prioritize where to spend engineering resources tracking down problems. This was a edge case that we could not reproduce, and had a very minor impact, and only affected a very small number of free users with a very specific configuration; a free user was able to track down the underlying cause and we fixed it.
