Blynk.Air OTA minimal code

You’ve fixed the code formatting in one of your posts, but not the other.

You have a similar topic about the same subject, and it’s always best to keep the discussion in one place.
To avoid cluttering-up this extremely useful and informative topic with detailed info about your hardware configuration, I’d suggest you go back to posting in your original topic and provide full info on the hardware that you’re using (including links to the Ethernet board you’re using and details of how this is wired-up to your ESP32), a fully working sketch, details of which version of the ESP32 core you have installed and details of which libraries and library versions you are using.

That way others may be able to replicate your setup and suggest solutions.

Pete.
