Do you have any idea to solve problem. ?

You can have a look at the log files at the server, maybe there are log messages written which help to find the cause.
Also you can try to start a Desktop-UI on a PC to check if a remote UI works.

When you are using a browser to show the UI the UI manager is started at the server and only graphical information is shown on the client (ULC UX client).

Remote UI ( ULX UX ) is working on the pc chrome browser.

only mobile version is not working.

Below is log on the web server when I tried to connect ( This log was showing in 2 or 3 second after error message was showing on the mobile phone.

WCCILdata (0), 2021.09.15 16:14:06.782, SYS, INFO, 4, Connected to (SYS: 191 Ui -num 202 CONN: 1) @ ::ffff:192.168.11.46 (::ffff:192.168.11.46)

I connected with server but I met another problem.

I added MultiPlexing Proxy on the project console and comment out #mxProxy = "none" on the config file.
Then mobile ui was connected.


It is showing login page on the mobile . but I want to show my screen instead of login page.
when I show it on PC. the url is http://192.168.11.40:6100/data/ulc/start.html then it is showing my page.


Below is mobile version log, I push the server on the mobile few second, then send the log to server.

The settings for MxProxy must fit on the server and client.
You can check if your are using a config and a config,webclient file and which settings you have made.

If you need further assistance you can possibly get in contact with your common WinCC OA support.
