OpenAPI Generator (C#, .NET6) - Extremely slow http requests under certain conditions

I used OpenAPI Generator to generate a C# client for the Thingsboard REST API. I then used this client to build an application for automatically creating devices and writing telemetry data into Thingsboard.

When I work from home and connect to my company network via a VPN, my application works just fine and is reasonably fast. However, when I work on site I noticed that every single http request towards Thingsboard (hosted on a VM in our company network) takes literally forever (up to 30 seconds) and I have no idea, why. It does not matter which API function or endpoint I call, they are all slow.

I already debugged this to the point where I can say for sure that the delay is caused somewhere inside this function call which is implemented in RestSharp.RestClient:

response = await client.ExecuteAsync<T>(req, cancellationToken).ConfigureAwait(false);

As this is deep inside the auto generated client code, I don't really know how to debug this any further. One important thing I noticed is that this problem is 100% limited to the application itself, and not to my whole system/connection. For example, when I call the API via Postman or directly in my browser, it works just fine and I get a response within less than 1 second.

What could be causing this problem and how can I debug it further?

It Depend on the where server location is. If it's in your office it will give fast Response. If Server is in one country and you are in another country it will give slow response
