Trying to build a Nextion display dash and im having issues. I have the Nextion display hooked up to a USB to TTL module, RX to TX, TX to RX and it is getting power because the display is on and working. However, whenever i try to upload the file through the Nextion editor, it wont connect and gives the message "Connection Failed, Forced Interrupt". Iv looked all over the internet and it seems other people have had the same issue but no one has said how to fix it. Does anyone have any input that may help? Thanks

This is what I did just fixed. Make sure to press Device in nextion editor and select the correct model, eg this will be found on the back of the display. Mine for example is the 3.2 touchscreen so that was under the enhanced tab. Next make sure the screen is directly plugged into the pc, no extension cables or hubs etc. Then compile then upload.
