Polling tentacles cannot download packages from TeamCity

Legacy Execution

My polling tentacles are unable to download the NuGet packages from my TeamCity server; if I connect via the server UI to the TeamCity feed and search for the deployment packages then I can find them, but when it comes to running the deployment, I get an error like this (see attached error log):

Attempt 5 of 5: Unable to download package Employgroup.Services.DataExport.11.3.0.21571-rc3 from NuGet feed 'TeamCity Feed' at https://teamcity.aussiepay.com.au/httpAuth/app/nuget/v1/FeedService.svc/: Error downloading Employgroup.Services.DataExport.11.3.0.21571-rc3 from http://teamcity.aussiepay.com.au:443/httpAuth/app/nuget/v1/FeedService.svc/download/Api_DataExportService_Trunk_Release/23351:id/Employgroup.Services.DataExport.11.3.0.21571-rc3.nupkg

The tentacle is happily polling away at the server, so basic network connectivity appears to be working - any idea why it can’t retrieve the package that it knows exists?

FYI TeamCity is v10.0.4 running on Windows Server 2016 (the same server as Octopus Deploy server); it is running behind an IIS reverse proxy (so that I can get the https://teamcity.aussiepay.com.au URL)

Hi David,

Thanks for getting in touch.

I think you are seeing the Octopus Server fail to download the package. Unless you have configured it otherwise, the Octopus Server will download the package from your NuGet feed and then send the package to your Tentacles. From your logs it looks like it’s the download on server part that is failing.

If you haven’t already done so, you could try enabling NuGet v2 on your TeamCity server by adding teamcity.nuget.api.version = v2 to internal.properties (https://teamcity-support.jetbrains.com/hc/en-us/community/posts/206817105-How-to-enable-NuGet-feed-v2).

You could also try using localhost instead of your TeamCity url if your TeamCity and Octopus servers are running on the same box to rule out some kind of strange proxy issue.

Cheers,
Shane

It looks like the problem was the interaction between TeamCity and IIS; I removed IIS and had Tomcat serve up the HTTPS and things are working again.
