WARNING GPIO4 is a Strapping PIN and should be avoided

[fabuena]

When I am configuring KC868-A8 to connect with Home Assistan by Ethernet I received this message

WARNING GPIO4 is a Strapping PIN and should be avoided.
Attaching external pullup/down resistors to strapping pins can cause unexpected failures.

What does it means?

How can I solve it?

don't worry, just forget the warm, it's no problem.
