Hi there, i think i'm the guy who reported this via the red hat support system but we never actually mentioned 7.1 in the tickets. I'm curious if this bug really applies to 7.1 as well because it's gone for us in 7.2 and reappears in 7.3 and 7.4 beta.

(Just to let you know).

Sincerely,
Tim Kopplow

Tim,

> it's gone for us in 7.2 and reappears in 7.3 and 7.4 beta

What do you mean by "gone for us in 7.2"? If you can please elaborate on exact behaviors, that would be very helpful.

Sorry for being so unspecific. The phrasing was also a bit incorrect. 
What i meant was that the subscription manager works perfectly fine for us in 7.2 but not in 7.3 and above. I was confused that after Josh Foots tested it it was marked as a bug in 7.1. We haven't tested it in 7.1 but that would be quite weird, wouldn't it?

> Broken in 7.1, Fixed in 7.2, and back to be broken in 7.3.

I'm going to test it with the release version of 7.4 tomorrow.

Alright. Tested it again in 7.4 (release) and the issue still occurs. What other infos could be useful for you?

> What other infos could be useful for you?

The behavior of the proxy with respect to consumer certificates. If the proxy is intercepting (man-in-the-middle) communication between subscription-manager and RHSM, then what certificate is it using to re-encrypt the communication? Especially does this behavior differ between 7.2 and 7.3?

One possible cause for the difference in behavior: the default URL for RHSM changed in 7.3 to subscription.rhsm.redhat.com from subscription.rhn.redhat.com .  You can try changing it back (by editing /etc/rhsm/rhsm.conf) on a 7.3 install to confirm if this is the issue. If this is the issue your proxy probably needs updated configuration (to configure subscription.rhsm.redhat.com similarly to subscription.rhn.redhat.com).

Yes Kevin,
The default hostname was changed from "subscription.rhn.redhat.com" to "subscription.rhsm.redhat.com" by RFE Bug 1278472 and first introduced by python-rhsm-1.16.6-1 and newer.

This could easily be the cause for an SSL error for a proxy environment that is only configured to pass the former "subscription.rhn.redhat.com".  For compatibility, customers should update their proxy servers to tolerate both hostnames:  "subscription.rhn.redhat.com" and "subscription.rhsm.redhat.com".

That's absolutely the reason and resolves our problems. I edited the URL in the config file and it worked like it is supposed to. I'm going to hand over this to the people that are in charge for our proxy.

I assume then that we're just the one who didn't get the memo? I don't know how i should've known that this action is required now. 

Anyhow, thanks for the help!
