Hi All,
I have recently tried to set up the dynamics crm for phone express app for a client. They are using CRM 2015 on-prem.
The user security role has the relevant permissions, and I have set the relevant entities to be available for phone.
On the server internet facing deployment has been setup and the ssl certificate has been setup.
When I open the app, I type in the URL for the crm instance but when I click Go I get the below error. Has anyone else seen this?
