Show white page after restart ServiceDesk Server

Hi All,
I am a new user for ServiceDesk Plus and I tried to update the security setting for the website.
After I update disable HTTP, disable domain dropdown, and set Content-Security-Policy to "script-src 'self'". After restarting the server, the webpage shows white page (no content). What should I do to resume the service? Please check the log below FYI:

BTW, my supervisor asked me to import the intermedia certificate but I have no idea how to import the certificate. What should I do to import the intermedia certificate?
