IFTTT : Webhooks failed to access WEMOS WebBroweser

[SkalarVector]

Hi All,
I have a Wemos web-browser with several functions such as :

server.on("/light_on", HTTP_GET, {
server.send(200, "text/plain", "");
WrEEPROM (Action_Params_Addr+1,0);
WrEEPROM (Action_Params_Addr+2,0);
WrEEPROM (Action_Params_Addr+3,0);
client.flush ();
});

The server is working on port 7070 (see jpg below).

1. The router configured to FWD external 7070 port to the internal address+ port 7070
2. The site is published using NO_IP (DDNS )
3. The site) and the command passing "http://my_site.ddns.net:7070/light_on" can be accessed from outside (external cell phone carriers for example) with no problems at all so seems like the port forwarding the the DDNS are working fine.

But, while activating the below applet I got the "Applet failed - timeout" see below (and it actually does not reach the webserver).
If I replace the url with Google url for example the applet works fine.
Any help/suggestion is blessed.

Thanks a lot.
