-#### Troubleshooting
-
-If OTA update fails, first step is to check for error messages that may be shown in upload window of Arduino IDE. If this is not providing any useful hints try to upload again while checking what is shown by ESP on serial port. Serial Monitor from IDE will not be useful in that case. When attempting to open it, you will likely see the following:
-
-![Arduino IDE network terminal window](ota-ide-network-terminal.png)
-   
-This window is for Arduino Yún and not yet implemented for esp8266/Arduino. It shows up because IDE is attempting to open Serial Monitor using network port you have selected for OTA upload.
-
-Instead you need an external serial monitor. If you are a Windows user check out [Termite](http://www.compuphase.com/software_termite.htm). This is handy, slick and simple RS232 terminal that does not impose RTS or DTR flow control. Such flow control may cause issues if you are using respective lines to toggle GPIO0 and RESET pins on ESP for upload. 
-
-Select COM port and baud rate on external terminal program as if you were using Arduino Serial Monitor. Please see typical settings for [Termite](http://www.compuphase.com/software_termite.htm) below:
