502 Welcome (fx39.iad).
Check your newsdemon user and password, and fill them out correctly in SABnzbd.
BTW: I would expect you get a "Failed login for server news.newsdemon.com" as soon as you start downloading. Can you check that?
The meaning of response code "502" in the RFC https://tools.ietf.org/html/rfc3977
- Code: Select all
If the client is not authorized to use the specified facility when
the server is in its current state, then the appropriate one of the
following response codes MUST be used.
502: It is necessary to terminate the connection and to start a new
one with the appropriate authority before the command can be used.
Historically, some mode-switching servers (see Section 3.4.1) used
this response to indicate that this command will become available
after the MODE READER command (Section 5.3) is used, but this
usage does not conform to this specification and MUST NOT be used.
Note that the server MUST NOT close the connection immediately
after a 502 response except at the initial connection
(Section 5.1) and with the MODE READER command.
That's a bit cryptic. But when I try newsdemon with some fake username/password, I get "502 Authentication Failed" in the pink box. So 502 ... correct your username/password.
I'm confused that/why you get "502 Welcome" ... 502 means "refused", but then it says Welcome too?
Anyway: 502, so check your Newsdemon username/password
