The proxy settings were inadvertently added to a release before we were happy with the full proxy support of all features. For example, some of the connection types went through the proxy and some did not.
To avoid user confusion we’ve temporarily removed the proxy configuration settings until we fully support all connections over proxies.
Hopefully when the full addition of Proxy Server settings is added it will also overcome the problem with the “Tunnel establishing timeout” that I have been experiencing
Yes, that’s exactly what we expect. The tunnelled traffic is being blocked as it’s not using the proxy settings and/or is on a port blocked by a firewall.
