Describe the bug We are getting intermittent failures when calling graph.microsoft.com. The exception isn't very clear and its been very difficult debugging the issue. I haven't actually been able to reproduce it locally.

Our app is a .net core 2.1 app running on Kubernetes. We try to get user memberships with the following code

var memberIds = await graphClient.Me.TransitiveMemberOf.Request(userOptions).GetAsync(); userMemberships = memberIds.Select(o => o.Id).ToList(); while (memberIds.NextPageRequest != null) { memberIds = await memberIds.NextPageRequest.GetAsync(); userMemberships.AddRange(memberIds.Select(o => o.Id).ToList()); } Its not clear from the trace where the error actually is but the lines above are the only ones which we call graph so we tried wrapping this in a try catch:

try { // get members } catch(ServiceException e) { // log something } Here is the exception trace:

System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw: The exception message

The SSL connection could not be established, see inner exception. Unable to read data from the transport connection: Connection reset by peer. Connection reset by peer To Reproduce I have not been able to reproduce. I've managed to force a similar exception by blocking graph.microsoft.com on my local machine. This gave me the following: click here for screenshot This error actually was caught in the try catch so I am baffled as to why the other one didn't.

Expected behavior I expected a ServiceException with better explanation of the problem and how to resolve it

Package Version Microsoft.Graph: v1.17.0 Microsoft.Graph.Core: v1.18.0

Additional context I've been reading a little and it may be due to socket starvation. Is there any way I can avoid creating a new Graph service instance every time. I can't find much material which tells me if this is possible. I know that you can do that with a httpclient instance and keep reusing it. I can see there is a GraphClientFactory but nothing on how to use it or if you can reuse it.

Please if you could provide insight it would be great. Thanks
