Upon further investigation, it appears that the certificate used is proper[1]. Does Duplicity use a stored certificate for verifying the connection? Why would this error being happening?

hey Eric,
afaik and according to
https://en.wikipedia.org/wiki/Wildcard_certificate
"
Limitations
Only a single level of subdomain matching is supported in accordance with RFC 2818.[7]
"
so the error is valid. where does 's3-us-east-2.amazonaws.com.s3.amazonaws.com' come from?
see
https://www.ssllabs.com/ssltest/analyze.html?d=s3-us-east-2.amazonaws.com.s3.amazonaws.com
also note from your info above
s3-us-east-2.amazonaws.com.s3.amazonaws.com
is not the same as
s3.us-east-2.amazonaws.com
the aws docs above seem to say
s3.us-east-2.amazonaws.com
s3-us-east-2.amazonaws.com
(prefixed 's3.' or 's3-') are valid [0] .
what is you command line (especially the target url)?
