How to determine if client is blocked by a firewall?

eabase opened this issue · comments

Hi,

I'm behind a corporate firewall, and trying to determine if my connection issues are due the firewall or local (Windows) Group Policy settings or if it is my client settings that are wrong.

Is there a simple way to determine if the client is actually reaching the server?

My assumption is that a simple ping to the URI is not a good test as it would use ICMP and not a TCP or UDP.
My suspicion is that you just get an SSL originated timeout error (as I reported in a different issue. #66 ), shown as:
handshake failed: -26624.
