Avaya Vantage k155 & K175 not display any contact from IPO Server Version 11.0.4.4

[Liton2020]

Hi, I have a server edition, with J139, k155 & K175
J139 is ok and can access the system directory Also Personal Directory From IPO Server.
But The K155 & K175 cannot, I found one previous thread regarding HTTP instead of HTTPS, and I have tried both methods but It fails to display any contact from IPO.

The server is 11.0.4.4 build 11
The handset is Avaya Vantage Connect Version 2.0.0.0.
Please anyone to solve this problem.

What 46xxsettings.txt file are you using. Asking as just read Avaya bug report where the issue was an old non-autogenerated settings file so it lacked key settings needed for the IP Office version of Vantage phone support.

Stuck in a never ending cycle of file copying.
