"Else contact ThingPule Support and provide the MAC address..."

Question

I'm getting this error on my ESPaper 4.2.

MAC address: 84:0D:8E:88:F1:98

Has stopped collecting the image form the server. No issue accessing the system from the connection it's linked to.

Comments

I'm a little further - I re-flashed the unit with the latest code from GitHub as I think this may be the issue (as per another thread on here). However, it refuses to get NTP:

I appreciate this suggests a network issue, however I can't see how it is - other devices with essentially the same settings (including a different ESPaper) work fine.

Odd!

If you compile the app yourself we don't have any control over which ESP8266 Arduino-core and library versions you use. That may or may not be the reason for the NTP issue.

You can download our standalone App Fairy at https://github.com/ThingPulse/app-fairy/releases to flash a pre-built binary. You can get the same binary used in the OTA upgrade process from https://services.espaper.com/firmwares/Espaper42Bw-PROD-V031.bin.

Please try that and report if it makes any difference.

Have you tried a simple NTP example from the Examples folder in the IDE
