I use "x = ThingSpeak.writeFields(myChannelNumber1, myWriteAPIKey1);" in my code to update the ThingSpeak channel. 4 fields are associated with this channel. This statement is executed about once every 5 minutes.
Roughly 60% of the time, I got an error message "HTTP error code -301". The other 40% of time the channel update is successful. What does the "HTTP error code -301" mean? Any suggestion on how to improve the success rate of the channel update
