Консольное приложение, перенесенное с .net core 2.2 на .net core 3.1, перестало разрешать внешние HTTP-вызовы

У меня есть консольное приложение с размещенной службой, упакованной в контейнер докеров в netcore 2.2:

FROM microsoft/dotnet:2.2-sdk AS builder
WORKDIR /service
# copy csproj and restore as distinct layers
COPY . .
RUN dotnet restore ./Project.sln
# copy everything else and build
COPY . .
RUN dotnet publish ./Project/Project.csproj -c Release -o /service/out

# build runtime image
FROM microsoft/dotnet:2.2.0-aspnetcore-runtime
WORKDIR /service
COPY --from=builder /service/out ./
ENV ASPNETCORE_ENVIRONMENT Production
ENTRYPOINT ["dotnet", "Project.dll"]

Я без проблем использую RestSharp 106.6. Затем сегодня я решил перейти на net core 3.1, поэтому, помимо успешного изменения версии сборки во всех проектах и ​​успешного запуска консольного приложения, я изменил свой Dockerfile:

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS builder
WORKDIR /service
# copy csproj and restore as distinct layers
COPY . .
RUN dotnet restore ./Project.sln
# copy everything else and build
COPY . .
RUN dotnet publish ./Project/Project.csproj -c Release -o /service/out

# build runtime image
FROM mcr.microsoft.com/dotnet/core/aspnet:3.1 AS runtime
WORKDIR /service
COPY --from=builder /service/out ./
ENV ASPNETCORE_ENVIRONMENT Production
ENTRYPOINT ["dotnet", "Project.dll"]

Затем я начал получать следующую ошибку при использовании клиента restsharp:

The SSL connection could not be established, see inner exception. Authentication failed

Но внутреннее исключение говорит то же самое. Я предполагаю, что в образе докера чего-то не хватает, что мешает работе клиента, потому что он работает локально - я не думаю, что отсутствует какая-то конфигурация, иначе локальная версия тоже не будет работать.

Ребята, вы сталкивались с этой проблемой раньше?

Спасибо

ОБНОВЛЕНИЕ

Я выхожу из фактического сообщения об исключении, которое я получаю при использовании RestSharp:

Вот только я снова откатываю проект, использующий .NET Core 3.1. Если это останется в .NET Core 2.2, он просто работает. Код для выполнения HTTP-вызова:

public async Task<MyResponse> GetAsync()
        {
            MyResponse myResponse = null;

            var stopWatch = new Stopwatch();

            stopWatch.Start();

            try
            {
                var request = new RestRequest(Method.GET);

                request.AddHeader("Accept", "application/json");

                var restResponse = await _restClient.ExecuteGetAsync(request);

                if(restResponse.IsSuccessful)
                {
                    gobResponse = JsonConvert.DeserializeObject<MyResponse>(restResponse.Content, DateTimeConverter);

                    Logger.Info($"Retrieved my response. Took: {stopWatch.ElapsedMilliseconds}ms. StatusCode={restResponse.StatusCode.ToString()}");
                }
                else
                {
                    Logger.Error(restResponse.ErrorException.ToString(), "Error performing request");
                }
            }
            catch(Exception ex)
            {
                Logger.Error(ex.ToString(), $"Error executing HTTP client");
            }

            return myResponse;                
        }
