A long while has been trapped on Mainkya Chaypa during the configuration of the MTA-STS Policy File for seosiri.com on IIS and the only problem is with URL Path after the .well-known folder.

Wrong URL - https://mta-sts.seosiri.com/.well-knownmta-sts.txt
Desired URL - https://mta-sts.seosiri.com/.well-known/mta-sts.txt

Seeking support to host the MTA-STS Policy URL on IIS for the Desired URL - https://mta-sts.seosiri.com/.well-known/mta-sts.txt

Let me know the unfolding of the right path either here or there-

Thank you
