FrontEnd error: "General error: The requested URL was not found on this server"

[phila6]

Hi,

This is a new install(and thank you for making this, very curios about NFsen updated fronteng). After install and starting the backend process, when opening frontend page I see an error: General error: The requested URL was not found on this server

Not sure where to go and how to troubleshoot.

Thanks,

Hi,

Do you have something additional that could be used to help you ? Some log messages for both apache and nfsen-ng could be useful to help you somehow

Hi,

There is nothing meaningful in apache logs. Where does nfsen-ng log to? And what should I set log level to?

Hi,

What OS is nfsen-ng running onto ? I tried to deploy nfsen-ng on two test servers and it works out of the box. I therefore assume that this comes from either an error in following the installation instructions, the missing configuration of settings.php or missing nfcapd data (nfsen-ng is only a visualizer, it wont do anything if you miss data).

(*) a common mistake that could lead to the capture you attached could be a wrong configuration of the apache configuration file. Double check that you have this for the directory "/var/www/":

<Directory /var/www/>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
</Directory>

instead of that

<Directory /var/www/>
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>

Closing this because of inactivity.

Аt startup cli.php start I get an error:

@doneckglobus do you have apache mod_rewrite installed and enabled?

[Dona21]

@doneckglobus not sure if related or not but in any case, you mentioned the file "settings.php.dist:" however, please note that this is not used. You should rename it "settings.php". Cheers

Yes, I did according to the instructions for Ubuntu 22.04

It didn't help

I solved the problem - an error to configure

It is a pity, it is impossible to display graphs for one user
