Error Page after version upgrade 4.0.10 to 4.0.11

After installing the new Version I get this error:
Cannot access a disposed object.
Object name: 'SlimMemoryStream'.

Setup was successful (according to last setup step).

My URL: https://devpackages.tts-company.com/

ProGet is IIS hosted.

Product: ProGet
Version: 4.0.11

I would suggest to stop/start the web server, and hopefully it will be fixed after that!

Hi, I already done that. IIS reset, application pool recycled and service restart.

Ok, how to roll back?

Uninstall, then restore the old database, then reinstall the old version.

Is there anything new to this topic?

Unfortunately this is the only report of this error out of several thousand installations, and we have been provided no other debugging information, such as a stack trace, reproduction steps, etc.

So, I'm afraid we can't provide anything new unless you provide more information, or attempt to debug/diagnose further on your end.

I've also been able to reproduce this error in my Proget installation.

Cannot access a disposed object. Object name: 'SlimMemoryStream'. I also have noticed this error only after updating to Proget 4.0.11, as Sebastian mentioned before.

Details of the error:

I have only managed to reproduce this error while trying to browse the feed using the browser. The nuget repository, and the /nuget/{feedName} works properly.

This error only happens while acessing the feed to browse for packages while i am using a specific url to acess the application:

1 ) When i use the ip adress of the server as url. The server works propertly.

When i use the name of the server on our internal network into the URL( http://trendssrc01/feeds/default). The server works properly.
When i use the name of the server on our internal network into the URL, with the domain ( http://trendssrc01.intranet.enterpisedomain/feeds/default), while browsing on the server wich the proget server is hosted. The server works properly.
When i use the name of the server on our internal network into the URL, with the domain ( http://trendssrc01.intranet.enterpisedomain/feeds/default), while browsing from another machine ( I only tested that in machines that are in the same domain). The server DOES NOT works properly and throws the error "SlimMemoryStream"

Reproduction steps::

I Think i already gave all the details i could in the Details of the error section :)

Looks like a bug caused by accessing certain pages from clients that don't support gzip compression. We'll have this fixed in 4.0.15, which should be released today.

Thanks for the detailed report!
