issue with certificate generation

[cvkmohan]

self-verify of challenge failed, authorization abandoned. is the error message I am getting. Finally, command terminating with All authorizations were not finalized by the CA. No certificate is getting generated. Created the IAM sample policy also - but - not working. Struggling for past one month and could not make progress. Hence reaching out to you.

Run certbot with -v to see verbose logs.
