I am currently having trouble creating a HubSpot connector. I created a developer account and a developer test account in HubSpot as per AWS documentation and tried to connect, but “The redirect URL ‘[https://3rdp.oauth.console.api.aws’](https://3rdp.oauth.console.api.xn--aws-to0a/) does not match the registered redirect URL for the app, Authentication failed. Please contact the app developer. error. In my opinion, the redirect URL in the official documentation, “URLhttps://region.console.aws.amazon.com/appflow/oauth” does not seem to exist. What is the solution to this error? I used this document as a reference > **[HubSpot connector for Amazon AppFlow - Amazon AppFlow](https://docs.aws.amazon.com/appflow/latest/userguide/connectors-hubspot.html)** > > Connect Amazon AppFlow to your HubSpot account so that you can transfer data about marketing, sales, and customer service between HubSpot and AWS services or other applications. ---

Hi, might be too late, but I had the same issue as you experienced. I found the root cause to be due to the “simultaneous sign-in for multiple AWS accounts” feature - more here [Signing in to multiple accounts - AWS Management Console](https://docs.aws.amazon.com/awsconsolehelpdocs/latest/gsg/multisession.html). Once I disabled this AWS feature the AppFlow setup worked as per the documentation. Hope it helps. ---

Hey there! Thanks for your post. I moved this over to the 3rd Party Apps section since this about using a connector, not building one. Hopefully, this will help you get more eyes on your question. Best, Jaycee ---

Thanks for moving the section! What do you think is the cause about this error ?
