Seedbucket and Sonarr not loading

Couple of issues I am having currently:

1. Seedbucket loads up with a blank screen from any connection and IE/Chrome/Firefox tested. I uninstalled and reinstalled but still the same result after signing in.
2. Sonarr has recently started giving me a 504 Gateway Time-out from nginx, Before I hit the uninstall\reinstall on this I wanted to see if there was anything else I could do to resolve it and avoid losing my settings and database.

Any help appreicated.
