Connection to a force.com domain is not supported

[Gabriel Calancea]

I have a connection that has a custom url which has an .force domain not .salesforce domain attached to it and when trying to make this oath connection the connection is not launched in the browser in gives the following error which is attached to this issue.

Hi. IC2 uses the Salesforce CLI to create and manage OAuth connections. That message is coming directly from the CLI executing:

sfdx force:auth:web:login -a <alias> -r <loginUrl> --json

You should be able to reproduce the same behavior by running that command directly from the terminal. Assuming so, you would need to check with Salesforce on why it’s not allowing a connection to this specific login URL, though before doing that, I would make sure that your Salesforce CLI is 100% up-to-date and the same behavior occurs in the latest build.

Ok, so it’s a Salesforce problem. Thanks for your fast response @Scott Wells .

No problem. I wish it was something I could help solve myself. I'm sure that Salesforce will provide a quick resolution or workaround, though.
