Does anyone have an idea why my torch could stop working? When I go to it with winbox and click Start it just doesn’t work. When I run it from console the router hangs 
It worked before 
You should upgrade to the latest version, to 2.8.28 or 2.9rc7.
And if you problem still exists, contact support@mikrotik.com with attached support output file from your router.

Reinstall did the trick
