CWOP Connection Failure Error -3 name resolution failure

[William Lucid]

CWOP has been working up until a day or two ago, noted there were no reports those days for 24 hours when I checked CWOP reports .

Kaspersky firewall open for port 23 and 14580
Windows Defender:  ports 23 and 14580 are open.

Router is forwarding ports 23 and 14580 to my computer; not rasp pi running weewx.

Router has been power cycled.

You're doing something unusual with the mentions of Kaspersky and Windows Defender and routing at a minimum, so I'm not quite sure what your LAN looks like....the mention of port 23 in your logs looks unexpected too.

Regardless, if you didn't change anything and it stopped working, it's likely something on their end wouldn't you think ?

Given "name resolution" errors, I'd start with checking your DNS setup via the usual utilities.  One of them is likely on your pi already.   The examples below explicitly hit the google DNS servers to take anything you might be doing locally re: DNS out of the question for debugging....

Forgot I changed starting ipAddress on LAN setting of new router; change starting ipAddress back to old router setting.  

CWOP appears to be working now:
