Aha. Okay, it's a lead then. Maybe the same issue is happening on OS X, where it is also possible to disable a proxy on a system-wide basis. It's something to ask the user about anyway.

If anyone else has suggestions I'm all ears.

In that thread he actually had to go into the windows settings (not in lc)
and actually remove the greyed out non active proxy settings so they were
blank.  At which point LC decided there was no system proxy. My guess is
that the engine in a standalone does the same check, and on windows would
think there was a proxy even if it was inactive, if the information for the
proxy is still in the registry.

I still don't know if it would apply to a mac of course.

The "invalid" host URL is the same one all other users are contacting and
is the domain of my client. Only an occasional user is getting this error
when contacting the same URL(s), it works okay for almost everyone.

I'm pretty sure it's a machine-based issue, and my puny knowledge base
points to some kind of system setup. I'd guess it's a wonky hosts file from
what little I know about it, but it seems like his browser ought to fail
too in that case. Or maybe it just doesn't like Amazon.

Unfortunately, I’m probably almost as much out of my depth as you :-(

No, localhost shouldn’t matter if the app is trying to connect to a
remote server. I don’t think that LiveCode needs to know about ipv6 either
(or only at a very low level). My suggestion was based on ipv6 resolving
localhost differently from ipv4.

Does the error message give the hostname that was considered to be an
“invalid host address”?

Thanks Peter, but I'm afraid you're speaking Greek to me. Would

Does LC need to know about ipv6 or is that handled at the OS level?
Sorry to be so uninformed, I'm out of my depth here.

I don’t know if this will help but I believe host can get converted to
::1 under ipv6. I know that I used to have an issue on my OS X a few
versions ago and had to use 127.0.0.1 instead of localhost in URLs.

I'm not sure about the other users but the latest one is on OS X.
Could this affect Macs too?

OH, thought just occurred to me, based on something that happened in
another thread.  If they're on windows, and had a proxy set up at some
point, then the proxy was disabled.. The information about the proxy
still
shows up greyed in the settings.  And it seems that LC decides the
proxy is
still active even though it isn't.  The browser would work, because it
knows the proxy has been disabled.   The solution, is to clear the
proxy
information from the settings, even though the proxy settings are
technically already disabled.

  The hosts file can be set up to provide specific name to ip address
mappings.  99.9% of the time its not used, and if it is, its often a
hijack. Along with the hijack thing, its also possible that a proxy
has
been set up unbeknownst to the user, and its munging something as it
decides where they want to direct the user, rather than where the
user
actually wants to go.

Can you post some of the gibberish?

  Out of thousands of users, occasionally one can't connect and
repeatedly
gets an invalid host address error. What causes those? All users are
sending to the same server at the same domain. Naturally they all
say it's
only our app and never happens in a browser.

Everything I've found about it is mostly gibberish to me. Is this
something to do with the hosts file on the computer? The latest
report says
it happens on different networks (home and school) so I assume it's
specific to his machine.
