Server issues

[howieT82 2]

Ive been having isues with my server for the past month or so restarting my computer or modem would help sometimes but i couldn't connect even on my local network so i uninstalled and restored the server from a backup It ran fine for a week or so and then I started having the same issues now im getting an error message today for the first time when trying to access the server "Could not find a part of the path '\dashboard-ui\index.html'.

Could not find a part of the path '\dashboard-ui\index.html'.
