Wyze Lock Gateway Not Connecting

I have had a Wyze Lock & Gateway for almost a year. It has worked flawlessly until recently - one day the Wyze Lock Gateway started flashing red (no changes to my network). I tried to reset the gateway to connect to it, but any device I try will not connect - same message “Gateway Not Found.” I tried different devices, deleting the lock from the app, updating the app, changing my router, EVERYTHING. I tried contacting support, they keep asking me to troubleshoot my wireless network settings (which I complied with) - despite I had zero changes and this happened, and the actually connection to the lock is via bluetooth and that’s the issue - not wireless connectivity. I’m so frustrated and getting no where. Help please!
