#79456 Up to 4.x there was default dns configured in lwip.
At the moment there is no default, so if using static ip you have to provide dns address

#80465 All things considered it would seem that DHCP on your switch isn't working effectively (does, for example, your portable or potentially PC get a legitimate IP and passage?) or something is turning out badly while your ESP is recovering and setting a door (and conceivably even a substantial IP-) address from the switch electrical engineering.

You could attempt to clear your ESP with the goal that all is as new and glimmer a straightforward precedent customer that just acquires an IP address (and portal) from a switch and completes a basic GET-ask.
