Login Server unreachable (LE-52)

I’ve had an account for over a year so am not part of the group of recent adopters getting this error. I have been playing the last 2 days with no issue. This error just showed up this morning.

“[LE-52] Can’t connect to login server…”

Tried:
Reloading steam (3X)
Verifying game files
Reinstalling game
Server Status
Version 1.0.5.2

edit: note that, initially, I was being put in an endless login queue but now get this error whenever I try to login.

Fixed for now.

When I reset my internet connection, it immediately worked. Notes: I am wired and made no changes to the internet settings, myself. It is possible, but unverifiable as far as I know, that the connection had switched to wireless. Could be a red herring, though.
