Got it, ya, that "failed to DL certs is the killer. People who got that generally had to replace controllers. I'm on my 3rd controller.
Original #1, worked great, made it thru all of the updates, but the temp setting knob when adjusting temps would cause the digits to sometimes go down when turning slowly up.
Controller #2, fixed that issue but its WiFi radio would go weak after startup. Access point within 6ft normal signal strength reporting at -25 to -30db excellent. Then it would drop connections and show -70db odd. Traeger dragged feet for 4 months to get me a replacement, claimed backorder.
Controller #3, arrived with current firmware. So far works perfectly, solid signal (-30db consistent), best temp regulation compared with Fireboard, and zero disconnects.
So they can work well, but you have to be polite and stand your ground with any company.
If it would help you I could dig out my original controller and send it to you, to hold you over? Having control over the grill is pretty handy.
And since you are starting up, do research the Fireboard WiFi thermometers because you will soon find out that the Traeger's temp readings leave lots to be desired in both accuracy and alarming. The Fireboard's take temp monitoring to another level with Alarms, Logging, Live Data Sharing with friends while cooking, and even Apple Watch support. This may be the best tool you can add, along with a good instant read like a Thermapen MK4
