WireMock returns stack trace instead of a meaningful message, it is very misleading.
Repro: https://github.com/LevYas/WireMockNetRepro

It would be very nice to return a message, saying that the target is not available.

Preview version WireMock.Net.1.2.10-ci-13352 on MyGet should fix this 500 error, please test.

Tested. For me, it doesn't return "No such host is known.", but "No connection could be made because the target machine actively refused it.":

< HTTP/1.1 100 Continue
< HTTP/1.1 500 Internal Server Error
...
* HTTP error before end of send, stop sending
<
{"Status":"No connection could be made because the target machine actively refused it."}* Closing connection 0

Anyway, it's much better than a stack trace :D
But I think the test in your PR might not be stable.

I run the tests for netcore 3.1 and I noticed a difference there, so I just check on known.

I also used netcore 3.1, but on Windows, maybe that's the reason

OK, the difference is that I try to connect to a non-existing hostname.
And you try to connect to localhost (which exists) but nothing listens at port 5000.
