Hi @c-schuette_7781 , This error is occurring on the remote server (i.e. nuget.devexpress.com). This error can happen when a server is overloaded... so you're basically doing a DoS on DevExpress's server. You'll need to try again or contact DevExpress for help,. I believe that DevExpress wrote their own, custom NuGet server. We've had several issues with it in the past. While talking to them, you should also suggest they switch to ProGet ISV Edition like some other component vendors Best, Steve

Thank you. The problem seems to be caused by Web.ConcurrentRequestLimit setting. If the server receives lots of requests and needs to query itself, these requests will be queued when the limit is reached. So they never finish in time and the original request throws the timeout exception.
