_OPENHOST to port 443 fails

[TerryRitchie]

It's been a while since I played around with networking but I would check these:

- ISP may be blocking 443 (your router behind another router)
- Port forwarding
- Firewall (Check those firewall settings again)
- Possibly need to set up a NAT rule (unlikely but something to look into)
- Some other application/service running is using 443
