"Problem loading page"

Sonarr version (exact version): 4.0.2.1183
Mono version (if Sonarr is not running on Windows):
OS: Windows 10 64 bit
Debug logs:
Description of issue: After reboot, Sonarr loads and operates fine. If I shut it down (via sys tray, right click and select exit), then try to restart it, I get the “problem loading page” error after a few seconds, instead of the login prompt. If I ctrl-shift_exc, Sonarr is still there. If I then end task there, I can restart sonarr.

I don’t know how you want me to post the log file from Private bin. And a search finds nothing with the word “error” in it.
