Hey did you solve this issue? I am also getting a similar message and my GPIO0 is not grounded.
What else can be wrong?

You don't; proxy support is normally implemented on an application level.

So I can't find help for application-level queries here? Also, do any of the native API or functions support this feature?

Thank You.

Hi,
I have requirement where my ESP32 needs to connect to the wifi with a proxy setting. Where can I put in the proxy settings for the network in the ESP32?

Thanks.
