      Description

      Create a nuget group repository that contains a v3 proxy repository with a host name that does not exist in local DNS.

      Send it a browse request:

      127.0.0.1 - test [05/Nov/2020:10:39:56 -0600] "GET /repository/nuget-group/v3/query/beta?q=&skip=0&take=26&prerelease=false&supportedFramework=.NETFramework,Version=v4.7.1&semVerLevel=2.0.0%27 HTTP/1.1" 500 - 1905 61 "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.111 Safari/537.36" [qtp691490943-53]

      This will cause a 500 response from the group.

      Expected: An error in a proxy repository should be logged, but should never cause a 500 response from a group repository. The group should skip the repository with the problem, and process the remaining repositories in the group.
