Thank you Standa,
Option number 2 isn't possible at our site. Would you be able to
explain number 1 to me? I'm very green with mod_nss so I don't know how
to set this up.
The problem you're seeing is that in proxy mode, mod_nss is acting as a
client and it doesn't trust or know the issuer of the server certificate
it is contacting. So you need to get that CA cert (or chain) and add it
to the mod_nss NSS database.
You can add it ala:
# certutil -A -d /etc/httpd/alias -n <some useful unique nickname> -t
CT,, -a -i /path/to/ca.pem

Thanks,

I suppose that this problem is with CA certificate on remote server:
You have two possible solution:
1. add CA from remote server to your certificate database at PROXY
server
2. build mod_nss with a patch from this email
PS: I have already worked on a similar problem for our customer.
Have nice day
