title: Unable to Get DHCP Lease - dhcps: send_offer>>udp_sendto result ffffffff
body: <p>When connecting to an ESP32 in softAP mode from an ESP32 client, the client connects and disconnects just fine for a while. Eventually, the AP will show the following error:</p>
  
  <p>dhcps: send_offer>>udp_sendto result ffffffff</p>
  
  <p>The client connects but doesn't get a lease. If I try to connect from another device, like my
  iPhone, it doesn't get a lease either. If I set the client as static, it works just fine even after the server stops responding to DHCP request. Stopping and starting the DHCP server doesn't fix it.</p>
  
  <p>I'm using AsyncTCP (me-no-dev Oct 17, 2019 version) on the server. I'm using the 1.12.2 Espressif 32 board library in PlatformIO. (Didn't work with 1.12.1 either)</p>
  
  <p>Any idea why I'm unable to obtain a lease? Rebooting the AP does fix the issue so it doesn't appear to be an issue with the client.</p>
