Unable to Access portal using localhost:3001 for Experience builder Developer Edition

[AravinthkumarBalasubramanian]

Hello, 

I have installed Experience builder developer edition and installed the packages in both Client and Server side and I have started the builder. 

I have tried to connect to my portal using https://localhost:3001/ 
And I have the client Id from OAuth 2.0 

But I cannot access my portal using the localhost. I can open the portal in my browser normally and everything works fine. 

Why I cannot access the portal using the local host, Anything will be very help. Thank you.

If you installed the 1.13 version of builder, there is a bug using enterprise portal and you can connect arcgis online without any issues.

Thank you for the info, but I have installed version 1.11.

If you are trying to access your portal, then you will need to add the web adpator to the end of the URL, eg https://www.myportal.com/portal. When you connect to ArcGIS Online, you do not need to specify this.
