Hi,
Thank but like wrote MatthiasF, problem is Profilux side.

you don't need to try network debugging with telnet or other protocols or tools, this doesn't help at all

the connection to GCC should just work, we need no network capture etc.

check the ususal and obvious things:
- WiFi (SSID, key, mode, etc.)
- IP gateway subnet etc.

make also sure port 10001 is not blocked

if this all is ok it must work

Hello,

After rebooting the profilux, the problem was solved.
As MatthiasF said, the server listening on port 10001 was not available and closed the connection:
Trying 192.168.240.94 ...
Connected to esp_b17150.lan.
Escape character is '^]'.
-> Connection closed by foreign host. <-

Nothing to do with my connection or a firewall, especially that I could connect to the P3, proof is given by the fact the reboot of the P4 has solved the problem.

Without insinuating that it was planted, maybe I had badly closed GCC the day before and the port tcp was not released properly (the server listening on port 10001 can only serve one user at a time )
Maybe this will never happen again :-)
