    Hello Everybody,

    just noticed with Wireshark, that TCP connection is closing after Arduino sends something!

    UDP does not do that with the same sketch!!!!

    It is closing after 2 MICROSECONDS not Milliseconds.. so it means, that TCP does not wait for anything and just closing...

    Did somebody noticed that too?

    i am working with a latest DEV branch.

    Thank you in Advance!

    Arduino Mega 2560 with iobroker.net (MQTT, node-red, etc..)

      Hello Everybody,

      checked yesterday and noticed, that if i use JUST STANDARD "TCP W5100) Sketch, it happens (Connection is closing just (2 MICROseconds) after Arduino sends something and just after that it starting to establish a new connection over the next TCP port!

      Checked everything with WIRESHARK.

      WHEN I USE STANDARD ETHERNET sketch, from the Standard Arduino Library Example:

      https://github.com/arduino/Arduino/tree/master/libraries/Ethernet

      everything is just fine!

      Should i place it as an Issue?
