Last night I noticed that my previously-working Govee LEDs had stopped working. While I cannot be 100% sure, I believe it was due to a brief power outage earlier in the day, which caused my router to reboot and assign a new IP address to my Govee. After requesting a new API and updating the API in PG3, things are back online. To guard against this in the future I have assigned a static IP address for my Govee. I don't recall reading anywhere that a static IP address is a requirement, but my experience leads me to believe it is. So if your Govee devices were working and then stopped, now you know one more thing to check.
