Obiee ver: 12.2.1.2
When I try to login to online rpd through BI12c Administrator tool , it throws the error:

So , as a test , i tried to download the rpd through datamodel download command , and it ask for the same rpd password , and it was successful , the rpd was downloaded successfully as the same rpd password was taken .
Isn't the datamodel download command and the BI Admin tool uses the same protocol ? I though it should go through obis server .
Can some one throw his/her view on this ?
Thanks
