Not that I know of. You'll need to tunnel through the proxy to really check the connection. I either do a proxy checker site to make sure nothing is leaking, or I just do the simple GET request against the site(s) I'm working with/on.
there is no more issues with the previous 2 dlls for some reason...
If anyone has the same issue, i found a solution!
I do not know why or how, but compiling the projects after the new installation/upgrade works for me.
