OK after further investigation I suspect it’s an EEPROM issue for the user with the Blynk myPlant AP name and maybe my PeaceFairApp AP.
Flashing sketches, bin files and “hello world” examples does not clear your ESP8266.
It clears RAM but not EEPROM. So if you have previously used your ESP with any other sketches that use EEPROM, like the Blynk my Plant examples then it will still be holding this data in EEPROM.
Ideally select a pristine ESP directly from it’s anti-static bag but failing this clear EEPROM before you start the ESPproMon provisioning process.
Below is a sketch that we use to clear all 512 bytes of EEPROM. We only use a few bytes of EEPROM but it makes sense to clear the whole 512 bytes. Ignore this sketch and use the one with OTA facility at Provisioning your ESP8266 with our server

The sketch above can be used to clear EEPROM at any stage if you get into difficulty with the EEPROM clearing features of the ESPproMon app.
