Unable to configure ASR with Hyperv and Azure

I have registered agent successfully, however while configuring protection group I am getting below error:- (I am configuring hyperv and azure ASR)<label class="recsvc-jobs-details-dialog-count-label checkbox-label"></label>

<label class="recsvc-jobs-details-dialog-count-label checkbox-label">Errors</label><label class="recsvc-jobs-details-dialog-count-text checkbox-label">(1)</label>

<label class="recsvc-jobs-details-dialog-error-message checkbox-label">The operation was stopped. (Error code: 535)</label> 
Possible causes The operation timed out. The VMM/Hyper-V/Configuration server couldn't communicate with the vault, connection to the Hyper-V host was lost, a manual user action was pending for a long time or an action on Microsoft Azure has timed out.

Kindly let me know the possible solution ASAP.
