repeated login prompts in PBIRS web portal/service URL

rupayan87 — Mon, 05 Oct 2020 18:45:54 GMT

when i use the default PBIRS wbeportal/service URL i can access the reports. However when i set up a custom URL, either on http or https, i get repeated login prompts. From browser developer tools, i see 401 error. Any ideas why?

I am using auth type - <RSWindowsNTLM/>

I am using a domain servcie account not the virtual one.

i referred below links but not luck.

The registry settigs is fine.

The solution is as below -

Add a new DWORD value in the registry path HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters

Value name: DisableStrictNameChecking

Data type: REG_DWORD

Base: Decimal

Value: 1

Add a new Multi-String value in the registry path HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0

Value name: BackConnectionHostNames

Data type: Multi-String

Value: <the report server URL>

Hi rupayan87. I am stuck at the same scenario as you, and the solution you suggested didn't help in my case. Any advice on what I can do next? TIA.
