Hi Alexacrm
I have a similar issue I am trying to connect to on premises at
https://stucrm.elluciancrmrecruit.com/
I get error
Unable to connect to Dynamics 365: Could not retrieve WSDL at https://stucrm.elluciancrmrecruit.com/XRMServices/2011/Organization.svc?wsdl. Check whether you selected the appropriate deployment type and that CRM URL and credentials are correct.
But I know those credentials I use to login to crm normamlly, is there something wrong with my url.
