Local networking IP address change causes Windy uploads to fail until weewx restarted.

I was considering whether to open this upstream on weewx but I haven't seen any other components fail on it this way, just this uploader.

Steps to reproduce:

• Verify periodic uploads work to Windy
• Have 2 saved access points on different networks (or an access point that hands out different local ip addresses when restarted)
• Turn off or reset the access point Weewx is connected to and let your device reconnect to the new one.
• Watch as all future uploads fail until Weewx is restarted

I will try to research and fix this. I think what might be happening is you specify the domain for windy's API and if uploads fail to it, this plugin or weewx runs a DNS lookup again and caches the failure.

What log looks like when it fails due to no connection.

This is what it looks like when it fails after the connection comes back. Apr 14 08:16:37 raspberrypi weewx[510] ERROR weewx.restx: Windy: Failed to publish record 2022-04-14 08:15:00 EDT (1649938500): Failed upload after 3 tries

No other failure messages like the debug had.
