Intermittent error using Gateway.send under load

We have a few endpoints in our API that call other internal endpoints and we are using the Gateway.Send method to do this.

Under load we are seeing the following ServiceStack error occur.

Could not execute service ‘GetMetacriticApiMovieByImdb’, The following restrictions were not met: ’ -[InSecure, HttpHead, HttpPost, HttpPut, HttpDelete, HttpPatch, HttpOptions, HttpOther, OneWay, Soap11, Soap12, Xml, Jsv, ProtoBuf, Csv, Html, Wire, MsgPack, FormatOther, AnyEndpoint, InternalNetworkAccess]’

The service endpoint works normally under regular load and cannot be reproduced in dev environment.


We need a repro to be able to investigate and resolve it.
