P4 10001's port closing connection this morning

[Gael]

Hi,

This morning i can’t connect to my P4 with GCC: "Loading system information … Please Wait" then "Could not connect"

Wifi is established
Ping to P4 IP is OK
WebInterface is OK
telnet to 10001 port is OK but disconnect:
telnet 192.168.240.94 10001
Trying 192.168.240.94...
Connected to esp_b17150.lan.
Escape character is '^]'.
Connection closed by foreign host.

GCC 1.1.1.1
P4 OS: 7.11
ESP Module: 6589

Connexion through USB is OK

I did not reboot the P4 to be able to do any additional tests / checks that can help you to diagnose.

Thank.

Gael

Hello Gael,

what does the GCC-Communication page say about the states of the WiFi-module?
Can you post a screenshot from there?

The wifi-module and host communication seems to be alive, otherwise states would not be checked and the
green wifi led were off, so the tcp-server seems not to forward or send the data.

But it is very hard to tell, where it got stuck or is unresponsive from this point of view.

OK, :-/

What do you suggest to me now?

Thank you :-)
