Android Eye4 connection issue...

Hello,
I have connection problem from my Mobile Phone (Sony Xperia Z2 , Android ver. 6.0.1) to my cam C7838WIP...
Mi native language is russian, and if i try connect to my cam  from mobile network (with Wi-Fi no problem found),
i see message "Wrong ID" (it connecting only1-2 times from 10), and if i change phone language to English or Hebrew, it work properly....
Thank you.
Viacheslav
