My station doesn't need to renew anything. It is a "dumb" La Crosse WS-2813 that needs my desktop to communicate for it. I use WUHU (https://en.wikipedia.org/wiki/WUHU_(software)) and if the PC is online, so is WUHU. So as soon as I restarted WUHU, it was communicating, and the lack of an error message tells me it's getting acknowledged.
I have the exact same PWS, a La Crosse WS-2813U, using the USB dongle on a WIN10Pro PC with WUHU and HeavyWeather; and sending to various PWS websites. You probably know already that all the bits can be balky sometimes.
Pull up your WUHU menu app/box (a "W" on the taskbar), select the "Setup" button on the right, select the "Weather Underground" tab. Then make sure the "Enable Uploads" is checked, "Upload Rapid Fire" if you want, verify the other fields.
Note if the "Uploads" count box has some number in it.
Then you can try unchecking the "Enable Upload" box, wait a bit, then check it again. The "Log" should show these actions.
If necessary, first use the "Stop" button, do the above steps, then hit the "Start" button.
Check the log, and on the Windows "Task Manager" app on "Performance/WiFi, look at your IP traffic and see if there's traffic (kind of moot maybe).
In short, set and reset some of the WUHU stuff, even go into Windows Services and turn WUHU off and on if necessary. Jiggle it around, kick it in the *** a little...
Maybe try a whole effen Win reboot.
Or the prob could be at WU.
Mine is usually bulletproof, but when it does act up it's a PITA. I've never seen WUHU/HW actually have any permanent/severe problems, or lose any data (it will reimage from the console, and even backfill the WU/MADIS/CWOP database).
La Crosse should/could have programmed a few more defensive checks into their systems, although they all seem to be pretty bad at making solid, defensive, selfsorting/checking software from following the issues around here... (I'm from a 'critical, multi-duplicated, redundant, life-death sys enviro', sloppy stuff irritates me).
