Does anyone know why I receive an 'invalid_grant: authentication failure' message when I try signing into Salesforce Workbench using a custom domain when I can sign into the custom domain normally? I keep getting this error message before being booted back to the login page for Workbench.
3Please make sure that your profile has "API Enabled" permission.– AyubJun 24, 2019 at 15:30
1Yeah, the custom domain should have nothing to do with login especially if you using oauth. I usually get that when I am logged in as another user and forget to logout. I would check permissions.– disasterloomsJun 24, 2019 at 20:50
I figured it out. I can only use a production account, not a sandbox to access. Must be a permissions issue on my end if this isn't the default behavior. Thanks!
