502 (Hit connection limit)

[Gfy]

When encountering a 502 error that indicates "Exceeded Max Connections" for a server, the execution should be paused for a while.

The problem with this is that the 502 error code seems to be shared with a lot of other errors too and different news servers have their own messages. Maybe test on "connect"?

It'll fail like this:

Connecting to 'news-eu.newsgroupdirect.com' failed.
Grab failed for <...@reader....eu> (filename.r48)
QUIT sent to main server. NOTHING created.
502 Maximum number of connections reached.
