HIU Portal access issue

@Shubhanshu_Shukla @neha.parnami

got access and logged into sandbox.ndhm.gov.in
Now, if I click on HIU portal, it asks for Client ID and Organization, when I enter submit, it shows a error popup “The client Id must have a unique value

Please help me overcoming this error, so that I can login into https://dev.ndhm.gov.in/hiu
