UDT cant access to the repository USR0013

Hi,

We are on BI4.1 SP3. I can access to BILaunchPad, and CMS. however, when I installed UDT and tried to access to the BI from UDT.

I got error as below screenshot. I have refered KBA 1806408, and made the changes as the note, and also added the ip address, and myhost.mycompany.com in hosts file on the desktop which installed UDT.  On server and client machine, firewalls are turned off. related ports are added on both client and server.

however, when i tried to logon via UDT, I still got below error. Could anyone please help.

Thanks,

Youqin
