Router port closing

[chrisncc1701]

Hi, I still have the problem of the router port closing after a few hours/days, (issue #313) i have changed the port number and all libraries are up to date, the 8266 becomes unavailable due to the port being closed but if i log on locally the serial output say's "connection received" the port reopens and all is ok

[mdhiggins]

If the local requests are working and the serial output is fine then this is a networking problem you'll need to investigate.

I've never heard of a router closing a port on its own, that would be bizarre. Is the port forwarding setting still in your router configuration?

Is it possible your external IP address isn't just changing? Lots of ISPs use a dynamic external IP address that may change at varying frequencies

[chrisncc1701]

the external IP address isn't changing and the forwarding settings on the router are still ok and there's nothing on the router logs, it just appears that the router thinks there's no connection so closes the port, but i know what your saying about being able to log on locally, as far as the esp is concerned it's still connected, the forwarding rules are TCP/UDP, don't suppose there is any way of restarting the ESP when the port closes, i don't understand how i can log on locally when the port is set to 303, i appreciate it could not be a problem with this project but any help from anywhere would be appreciated

[mdhiggins]

This is definitely odd behavior and something that would need to be addressed at the router level, though I can't say I've ever heard of a router doing that. Having the ESP restart isn't really a great solution as the device itself isn't doing a deep sleep or anything, it should remain connected and listening continuously while it's on. Nothing on the serial output suggests the device has crashed or is rebooting or anything does it? Does the uptime counter reset or anything on the local page?

What kind of router?

[chrisncc1701]

It is a Huawie HG633 router, i am going to leave a laptop on monitoring serial for when it happens again and also check the uptime, at the moment i don't think the service provider will take any notice

Try some of the solutions here

Looks like this is a specific problem with your router

[mdhiggins]

You can also try adding this line at 508 and see if it helps client.keepAlive();

  Serial.println("WiFi connected! User chose hostname '" + String(host_name) + String("' passcode '") + String(passcode) + "' and port '" + String(port_str) + "'");

  client.keepAlive();

  // Save the custom parameters to FS

Showing the above and below lines for reference

Hi, I tried that command but the device went into a continuous sort of restart, and i have looked at various forums about my router, and it looks like the port closes with inactivity but i don't know why the time interval varies sometimes it runs for over a day, i don't think talktalk are going to be much help, iv'e included the serial output withe the command on line 508, i have noticed that the parameters set in AP didn't look as though they where saved with client.keepalive(); on line 508

Try putting it at line 950 instead (remove previous change)

  irrecv.enableIRIn();

  client.keepAlive();

  Serial.println("Ready to send and receive IR signals");

[mdhiggins]

Compiles and runs just fine on my test device using line 950

[chrisncc1701]

thank you, have done that, will comment in a few day's, meantime i'll try get talktalk to send another router haha

[mdhiggins]

Feel free to continue discussion

[chrisncc1701]

Hi, Just to let you know, talktalk have been very helpful and sent me a new router a DG8041w and the help desk been on the case, the port now stays open, so don't know if the HG633 was faulty or just the way it did port forwarding, so big thanks for your help and great project

[mdhiggins]

Glad you got it working!
