Re: [OCLUG-Tech] Connection Reset Oddity

HTTP/1.1 needs a "Host:" Header. But also, I don't get the self-signed cert issue. Probably because I added it already.

Cheers

Usually yes. Another case where this happens is when the browser and the site cannot negotiate common ciphers. When I connect to prestocard.ca using Linux Chrome and Linux Firefox they both go to RC4-128 with MD4 MACs.

Have you eliminated the router as the source of the issue?

Can you telnet to prestocard.ca port 443 through the router?
There is no external router involved - my Linux box is connected directly to the cable modem.

I can telnet to port 443.  But this is interesting:

HTTP/1.1 301 Moved Permanently

closed

That's the end of the session (I entered the GET request). If I'm interpreting this correctly, the server is responding with a permanent redirect, but the redirect is pointing to exactly the same URL as I started with.

This gets weirder and weirder...
