Hi Dintee,

Thanks for posting in the community! I understand you're seeing a 'problem connecting to server' error when trying to generate the entry key for your Nest Learning Thermostat (3rd gen). I appreciate that you've already tried a Wi-Fi reset—no worries, I can definitely help you get your thermostat linked to the Nest app!

To better investigate this situation, I’d like to ask for a few details:

Since the Nest Learning Thermostat (3rd gen) has the entry key and QR code printed on the back of the display, can you confirm if you tried adding the device using either of those options?
When you mentioned resetting the Wi-Fi, did you perform that reset directly on the thermostat’s display by selecting Settings > Reset > Account Connection or Network?
Could you share a picture of the error appearing on your display? This will help me better understand what the thermostat is showing.

I look forward to your response.

Best regards,

Jenniffer
