Hmmm.. I'm having the same problem. I have a Profilux 3 eX (upgraded from a 3 to an eX) connected to the internet with a D-Link DAP-1522 Xtreme N Duo Wireless N Access Point.
I re-loaded the 5.15 firmware & have PLC 5.1.5.2. I have the web server port set to 80 with no password.
I have the external IP at port 80 and port forwarded to internal IP address with port 80.
The only thing I get is:
Connecting
Retrieving data
No response from the device
If I use the web browser on the phone I can get to it by using the external IP and the internal IP.
I've been using the Myprofilux v1.3 Android app since it came out and I can use the Local connection and Remote connection without any problems.
There is a myprofilux.rss file I have to load to the web server filesystem for it to work.
So, I deleted that to see if that was the problem...Nope..
Since I don't have a password setup for the web server I put one in the App to see what would happen.
It now says No response from the device (Wrong password).
It seems to me it is the App that has some sort of problem. Maybe the response time timeout is to short.
I just don't know.
We Need Some Help!!!
Thanks.
