Outgoing packets are permitted to use either, meaning that the NAT system in your router can get confused.
Mike->Actually the NAT system in the router handles that.
But onto the more important stuff: I interpret your response as saying that you cannot connect to the content server from your portable device (tablet?). That would mean that something between your tablet and calibre is blocking network packets. If it isn't the router then it is the AV/firewall on the laptop, which points a finger at avast.
Mike->No, it's fine. When it wouldn't connect, it wouldn't connect to either one is all I meant. Whatever rebooting the laptop did, cured both.
You could try rebooting the laptop in "safe mode", starting calibre, and seeing if CC can connect.
Mike-> While that sounds good, the cure so far to this has been a regular reboot, so I suspect safe mode will work just fine and we won't learn anything.
If is can then we know that the problem is in software that is loaded while you laptop is booting, probably avast. You could try disabling avast to see if that fixes it, but my experience has been that avast is very hard to completely disable. You could look for avast logs to see if it is unhappy with calibre. You could also try rolling calibre back to what you had before.
Mike-> I'm pretty sure it is not Avast. There's no alert given (Avast is good at doing that) and nothing in the log. I also think that in the past - months or maybe even a year ago- when this happened for a week or two, I was using Microsoft's AV... (Security Essentials)
I am certainly willing to look at debug logs. It is possible that they might tell us something.

I'll be happy to share debug logs if you're curious or still interested. If this recurs and reboots work, I'll survive... and I don't want to impose too much.
