A new thread by me
Hi first,
Using AsyncClient from #include "ESPAsyncTCP.h", the NodeMCU connects to a remote server on the Internet using
.connect( IP, port);
This call is fine.
2 minutes later, I make the same call to another port on the remote server.
But it crashes.
Using ESP Exception Decoder I understood all that...
I will post the result of the ESP Exception Decoder

there are some more lines but not relevant
