[jitsi-dev] DNS resolution fails



In a corporate network again (new one this time, visiting client), and
I notice that jitsi is allowed to check if it's the latest version,
but can't talk to any of the XMPP services - results appear to be
blocked at DNS level.

But, pidgin works just fine and connects to the exact same services
(FB, google talk with same accounts).

Attaching a screenshot of the relevant packet capture - redacted first
two octets of IPs to protect network anonymity.

Any idea what's going on? Using latest nightly.
