Trying to run Http Reverse Proxy Sample, after compiling succesfully it fails when debugging throwing exception. Windows 10, Visual Studio 2017, dotnetcore2.0

Is there any specific config needed?

Hi @carloshm - My assumption is that the port is already listened on. When you have some other services running that listen on 8080 and 8081, that can certainly be the case. Run netstat -a to see what ports are currently open on your box. If 8081 or 8080 are used, use -b option to see who uses them. If you cannot stop them, change the code and replace 8081 or 8080 with another port. If that all does not work, running VS as admin might be try.
