Why does SDL Desktop fail to open, or show two “!!” in SDL Hosting?

There are no currently known root causes for this issue — treat it as an exception rather than a known pattern.

Before escalating, try: - Restarting the machine - For hosted towns: right-click the SDL icon in the system tray and select Log Out All RAS Sessions to force a fresh connection to SDL’s servers

If the issue persists, contact SDL Support.
