Hi Jorge Torres
Firstly confirm that the Azure subscription associated with the Bot service is the same one you are using in the Language Studio. This might sound simple but this is the reason most of the time,
Also Ensure that the resource is visible and accessible in the correct subscription. Confirm that your Azure account has the necessary permissions to access and manage the Bot service. Check the Role-Based Access Control settings in the Azure Portal.
Hope this helps, kindly accept if you find it useful thanks much.
