It may also mean that the "other side" aborts a connection that already has been established, in a rude way by sending a RST instead of the normal polite way using FIN+ACK. Webservers seem to do that often. In that case it's actually not an error.

That's probably not the library itself but the "espconn" "glue" that Espressif added.

It probably means the connection was refused; that "other site" (aka the "foreign host") sent a RST instead of a SYN+ACK in response to the SYN from the esp8266, which usually means it doesn't have an application listening on that port. Next step is the use of a network sniffer like tcpdump or wireshark.

I don't think liblwip generates any logging. A well-designed library shouldn't be logging anyway.

Is there a possibility to have logs from the library liblwip ?? (SDK 1.3.0)
