Issue:
You are receiving an error message that says The resource write operation failed to complete successfully, because it reached terminal provisioning state 'Failed'.
while deploying Azure Health Bot with a new resource.
Resolution:
You had tried around 4-5 times and it was failing. So you had to close and re-start a tab then it worked fine.
Seems like refreshing the browser worked fine.
