# Avoid Reddit's "Bad request" page using ServiceConnect["Reddit"]?

GROUPS:
 I'm sure there's some really simple thing I'm overlooking. When I enter this: ServiceConnect["Reddit"] ...the WolframConnector dialog comes up, as expected. When I click the "Sign in to Reddit" button, Reddit opens to a "BAD REQUEST" page, with this message: you sent an invalid request — invalid redirect_uri parameter. I never even get a chance to sign in. Am I overlooking something, or is there an option in Preferences somewhere that needs tweaking? Maybe a port the firewall is blocking? I'm stumped. I'm not doing anything fancy to get to Reddit. No VPN, no external router, nothing but the hotspot on my phone. I can generally access all of Reddit's services through Waterfox with no problem. I just can't connect Mathematica (Home Edition, 11.1.0) to Reddit.Any ideas? Thanks in advance.
