Re: Regarding - SHA-2 supported version in mono

I'd say trying a newer mono build first would be the best option. Either
4.2, 4.3 or master. SHA2 certs have been supported for a very long time, so
if you are still having issues maybe you could provide access to some certs
to reproduce the problem with?
