Not able to login Report designer

Please try using only the base URL format to access Report Designer: https://SITENAME.acumatica.com/

Your current URL includes extra parameters (for example, w(6) and CompanyID=Tenant), you can remove them, those values are used for tracking session and tenant context during sign-in and aren’t required to open or use Report Designer.

Hi ​@epan ,

Looking at your screenshots, one thing to check — it appears you are using https. Please use http instead.

Use the URL in this format:

http://localhost/YourInstanceName
  or
http://SERVERNAME/YourInstanceName

Also, please make sure:

You are using a clean base URL only (no extra parameters).
The Report Designer version exactly matches your Acumatica build version.

Hope this helps.
