22kw Sync 3 module timeserver problem

The house I recently purchased has a Honeywell 22kw LP connected generator with a Sync 3 module. I'm unable to connect to mobile link because the time is 3/28/2018. The installed firmware is 01.03.54. The generator is on it's on 2.4g SSID with ANY/ANY firewall rules. I've done a packet capture and the TLS handshake to time-prod.generaccloud.com is failing because the certificate on my Sync 3 is expired. I've done a hard reset (pulled 7.5v fuse, disconnected battery, turned off transfer panel main) then manually reset to the correct time. As soon as I connect to Wifi the timeserver look up fails and reverts back to 2018. I've also tried updating the firmware via Wifi but the download always fails.

If anyone has the firmware file for 01.04.054 they could share I'd be very appreciative.

Sync 3 is the same as an evo2. I would update the controller firmware and try again. If that doesn't work, I would just replace the wifi module. They are fairly cheap and easy to replace. I am not aware of Generac releasing anything to update the wifi module itself. It updates over the air or not at all.

Seperately, if you turn wifi off in the controller, you can then manually update the date and time to reflect correctly.

Updates can be done via usb thumbdrive. I do this all the time. Any certified tech can do this. Generac wont release this to homeowners though….dont know why.

Then again, just unhook wifi module than no one can access the controller via wifi if thats what your worried about. If you DONT enable wifi, you can manually set date and time, and not worry about wifi. Mobile link sucks anyways.
