Serviio

Hello!
Trying to access my media thru the web, I've checked that:
-I have a pro license and the console recognize it
-My media are well played via DNLA on my Smart TV
-I have set up a password in the remote tab of the console
-Still in the remote tab, the router is configured automatically to allow incoming web connctions, and I've entered my actual WAN IP
-Clicking on the "check connection status" button, I get "established connection"
-The Serviio server is active
-Typing http://localhost:23424/mediabrowser/#/browse gives the correct screen
-http://127.0.0.1:23424/mediabrowser/#/login gives the correct login screen

BUT:
-When I enter http://"my actuel IP":23424/mediabrowser I get only a blank screen, whatever the bowser I use ( Firefox, Chrome, Edge...); With Firefox, the status bar starts saying "Waiting for <myactual IP>....", then, flashing something that could be "Transferring data", then again "Waiting for <myactual IP>...." for several minutes, then a blank screen. Nevertheless, the Firefox tab shows "Mediabrowser", so it seems that the web request is correctly passed to the server, but Mediabrowser doesn't respond.

I've also checked that a ping <myactual IP> was OK, I disabled the firewall, I've established a NAT rule for the port 23424, and I verified in the Serviio log that this port was open.

I also tryed to unchek the automatic router configuration, and verifyed thet the port was open thanks the NAT rule, in vain.
I've really no idea of what is wrong....
Help, please!

A strange one - some things to check:

• What do you get if you use an external tool to check that port 23424 is open (eg: http://www.yougetsignal.com/tools/open-ports/)
• Can you access media browser from another PC/device on your LAN using your LAN IP address (generally a 10.x.x.x, 172.x.x.x or 192.168.x.x address): http://<my LAN IP>:23424/mediabrowser
• When testing, you are actually testing from an external network (3G/4G or something - ie. you're not relying on your ISP or router to reflect your external traffic back to you?)
• What is your WAN (internet) speed?
• In your router can you manually forward port 23424 to your Serviio server - this may be better than relying on UPNP to do it (automatic forwarding).

Thank you for your help.
Testing everything as you suggested, and browsing many fora, I finally discovered what could be the cause:
My internet provider (Orange) blocks the loopback function in their box (Livebox2); Hence, impossible to access the server from my LAN. Access from outside, or from my phone (provided the wi-fi on my LAN is set off), functions normally.
Again, thanks for your help!
