"context deadline exceeded" Error

Recently I have started receiving a "context deadline exceeded" error message any time I schedule a command to be sent from TeslaFi to my car. Back in January things worked successfully. I don't use scheduled commands every day so the next time I tried to use one was this past week & I got these errors. Why is this happening? How do I fix it? 

I checked my count of commands used & it shows that in February I have used Vehicle Data: 0, Commands: 0 (500 Limit), Wake Command: 3 (25 Limit).

The wake command is from the 3 days I have tried to use commands. The first 2 days I just scheduled the command to turn on the HVAC, and this morning I scheduled a wake command first & then 1 minute later the command to activate HVAC to see if maybe the problem was sending the command while the car was asleep, but it still does not work.
