GoneException

I'm trying to connect with my CosmosDB db using the SDK v.3.5.5 but got this error:

GoneException: The requested resource is no longer available at the server.
ActivityId: 25ec629e-7079-41f2-aa1a-f74f152f9da0, Windows/10.0.19042 cosmos-netstandard-sdk/3.28.2
Microsoft.Azure.Documents.StoreReader.ReadPrimaryInternalAsync(DocumentServiceRequest entity, bool requiresValidLsn, bool useSessionToken, bool isRetryAfterRefresh)

CosmosException: Response status code does not indicate success: ServiceUnavailable (503); Substatus: 20001; ActivityId: 25ec629e-7079-41f2-aa1a-f74f152f9da0; Reason: (The request failed because the client was unable to establish connections to 3 endpoints across 1 regions. Please check for client resource starvation issues and verify connectivity between client and server.

I'm able to connect using the old/deprecated version (DocumentDB.Core)

I ended up migrating our repos to the new Cosmos .NET SDK v3.
