Pfsense ntopng need help

can you help or point me in the right direction i am running into a problem and not sure were to turn too Ntopng keeps responding with THIS SITE CANNOT BE REACHED
I know that the subject has been talked about just wondering if there is something new and I missed it

Look for the error messages in:

the only thing i could find

and i notice that this keeps happing evetime i try to restart it it keeps stopping as soon as i refresh the page

If you are not familiar with using SSH to look at things from the command line, you could just download the pfsense config file and reload it. Might be the fastest path to getting this fixed.
