UDP services dos not work properly with LwIP_Ethernet

[Nourbakhsh-Rad]

Hi @d-a-v
I am using ESP12-E with ENC28J60 ethernet module for my tests
I tried to get the date-time with configTime and AsyncUDP (ESPNtpClinent library)
When I am using static IP, my sketch dos not work! but with DHCP everything is OK
It seems the UDP services dos not work properly with LwIP_Ethernet

Hi,

It seems UDP services work great with Ethernet too, because you say that it is OK when using UDP and DHCP.

When using a static configuration, did you not forget to register a DNS in your sketch ?
Without a DNS, your NTP provider cannot be resolved.
Indeed, when using DHCP, a DNS server is automagically registered.

This link might help you, it is the same exact issue (it is with WiFi not ethernet but still,exactly the same).

You should not be using my own repo but the public one for such question.
