When trying to connect through a proxy server TortoiseHg for Windows says “SSL error: unknown protocol”

Question

The scenario:

You\'re behind a proxy server on Windows. You\'ve configured TortoiseHg to use a proxy server; that is you\'ve entered a server name/IP and port numbe

Answer 1

In addition to your excellent tip, I offer one more...

If your company is using an automatic proxy script, then the proxy used for web browsing may not be the one you need for Mercurial. Thus if you try the proxy you find via netstat, and you get "getaddrinfo failed" errors in tortoise, then try this...

1. Get the proxy script address: IE->config->Internet Options->Connection->LAN ?Settings. Copy the url from the "Address" box.
2. Browse to that address and save the file to disk.
3. Open that file in notepad and scroll to the end, it probably ends with something like-- return "PROXY ipaddresshere:port" that's the IP and port you need.
4. Plug that IP and port into tortoise: right-click the repo, click settings, click proxy, put the ip and port into the Host field. I generally don't need user and password so try without it first.

Answer 2

The cause is that Internet Explorer is using an automatic proxy configuration script and TortoiseHg is using a particular proxy server. IE is not using the same proxy server because the automatic script picked a different proxy server.

The solution is to enter the proxy server used by TortoiseHg in IE's connection settings, or figure out which proxy server you're using at the moment and tell TortoiseHg to use that one. You may need to browse an external web site before TortoiseHg can connect.

You can figure out which proxy server you're using by browsing with IE and then running the DOS command:

netstat

and you'll see some connections in the Foreign Address column on port 80 or 8080 (common proxy server ports).
