For the last couple of days, my miners haven't been able to connect to stratum.  All I get is constant "stratum_subscribe timed out" message. I've tried multiple pools and multiple different coins (e.g. decred @suprnova, xmg @suprnova, ftc @coinotron, xmg @coin-magi, etc.)  No new hardware or software on my machine.  I just out of the blue got this.  My net is good, can still stream, play games, mine Burst.  I also tried rebooting modem/router, no luck.

Anyone have some advice? How to go about troubleshooting?  I have idle hardware and it's killing me!

Edit:
Windows 10
Wolf's m7m cpuminer
Various flavors of ccminer

My miner can't connect, and when I try to navigate to coinotron.com, Chrome says the connection is not private.  I tried a quick search, but everything I find is from a couple years ago when there were bad ddos attacks....  Any ideas?
