Changed CDN Prefix, can't access Rocket.Chat administration


I changed the CDN prefix in the Rocket.Chat administration settings but misspelled part of the path. Now the application won’t load because it can’t find any of the js/css resources so I can’t get to the administration settings to fix it. Does anyone know the environment variable that could be set to fix this or if there is a way to access settings on the serve from the command line. Or a different solution to fix the CDN prefix?
