[SR-Users] app_ruby - KSR::PV.sets method not found

Sun Mar 31 13:34:06 CEST 2019

Thanks Daniel!

You’re 100% right, that was the issue. Using a private variable I can see the change. I also had an exit in place before the relay to test, removing that I can see in Wireshark the request is being sent as expected.

Now I just have to figure out how to deal with UAC auth challenges!

Thanks for your help, as always :)
