What is going on in ThingSpeak recently? All my ESP's which use the ThingSpeak library have either stopped working or only are only posting data very sporadically. The error code is :"Problem updating channel. HTTP error code -301". I've gone back to the basic example in the ThingSpeak library (unsecured) and it doesn't work either - same error code -301. What has changed? HTTP error code -301 Generally the -301 indicates a connection problem. Are you able to try another network? Also, our security certificate was recently updated, which would also result in a -301 error. Perhaps be sure you have completely disabled all secure connections when you retry. (or start with a fresh version) thingspeak library error code -301

I am using the standard program WriteSingleField from the Thingspeak library to send a number between 0 and 99 to one of he fields in my channel. Every 20 seconds the field is updated in the Arduino program. But after two updates I get an HTTP error -301 and the channel is stops updating... I tried several things (changing my write api key, using a longer delay, ) but cannot find a suolution. My Arduino MKR1000 uses the WiFi101 library and this is also the latest version 0.16.1. I have not changed anything in my WiFi router. Who knows a solution?
