syslog & arduino mega 2560

Good day!

I've been trying to make friends with mega + ethernet shield w5100 and syslog for a week now (library

task to send messages to syslog server

Programs from the examples are loaded, but nothing comes to the server.

I can’t find anything similar in google.

With esp32 with the same library, everything worked out.

Has anyone encountered this? And how to make friends with them all the same? Sorry, this is google translator))
