Captive Portal /htdocs/errors/errorcode-413.html No such file or directory

[amalzz]

Hi.. Need an urgent support. I am getting the error "lstat failed for: /htdocs/error/errors/errorcode-413.html No such file or directory.

Also some devices have to reconnect with Captive Portal after every 5-10 minuets.

This is the second server which i setup in order to monitor the issue.

Cheers!
