No interesting log.

TO REPRODUCE

Steps to reproduce the behavior: Flash http://ota.tasmota.com/tasmota32/release/tasmota32-webcam.bin 9.5.0 on Ai-Thinker camera. Set-up Wifi. On your router, forward port xxxxx to esp32's port 80. Connect through lan : no problem. Connect over internet : very very slow.

EXPECTED BEHAVIOUR

A clear and concise description of what you expected to happen. Web UI should be a little less fast over FTTH

SCREENSHOTS

If applicable, add screenshots to help explain your problem.

First, you shouldn't do this. Tasmota uses HTTP with no encryption. It shouldn't leave your local network. You are going through the internet unencrypted...

Tasmota is very limited in RAM so it sends HTTP responses in 'chunked mode'. This means that small portion of response are sent through the network to make sure we don't buffer too much. This means a lot of round-trips between Tasmota and the web client. On a LAN it's not a problem, on a high latency network it is.

However you have maybe another problem on top of this one.

There's nothing we can do. Tasmota is optimized for MQTT.

Yup, I know but there is nothing critical shown by this camera.

On a LAN it's not a problem, on a high latency network it is.

Even over FTTH ?

Then you may have another problem. Using the developer tools of your browser might give you a hint about the problem

Good idea ! I think that I've found the problem ;

Web page try to load /stream from LAN IP even through Internet through external DNS/IP

<center><img src="http://192.168.1.234:81/stream" alt="Webcam stream" style="width:99%;"></center>

Could img src be relative and not absolute ? Could video stream be served through port 80 too ? Or could this hostname 192.168.1.234:81 be overriden by configuration (ExternalIP:secondPort) ?
