I have the problem connect ESP32 Ethernet using Ethernet_Gerneric.h library I Can't Ethernet.h because I want to host a webserver on my ESP32 and EthernetServer class in Ethnert.h doesn't have enough to host my Webserver ?

error when connecting to MQTTs Server

Solution Edit Ethernet_Generic library have file name "EthernetClient_Impl.h"
line 135: internetClient::write(...)
add "if(Ethernet.socketSend(_sockindex,buf,size)) return size;"
below if(_sockindex >= MAX_SOCK_NUM) return 0;"
