Doubt it. Your connection evidently got through (at least) the
authentication exchange, so basic data transmission seems to be
working. I speculate that there's something data-dependent about
the command that's failing.
As an example, it would not be terribly surprising to get a behavior
like this if there were something deciding to do an LF -> CRLF or
similar transformation on the data stream. The substitution might
accidentally not trigger during authentication, only to break some
actual query a bit later. But there really shouldn't be anything
making such changes in our data stream.
Still, looking at recent network-level configuration changes wouldn't
be a bad idea.
