XRMToolbox cannot connect to Dynamics CRM

Question

I'm using the XRMToolbox normally and it suddenly cannot connect to Dynamics CRM anymore. I still can access to dynamic CRM normally but now I cannot using XRMToolbox. This is the error message.

Do you guys have any recommendations???

Answer 1

Experienced same however have it now working via an SDK Login Control connection and next Office 365 sign-in (instead of the earlier Connection Wizard connections which seemed to stop working)

Answer 2

I fixed this by reset the password. Still dont know what is the root cause of this issue :D
