What could be the problem with LookingGlass?

Question

Ping

Installed the following LookingGlass on the server . I followed all the instructions, installed the required add-ons for PHP, its version also corresponds to the required one.

In this case, only "host" works from the commands. Neither ping nor mtr nor traceroute work. But there are no errors either. Just "Loading" and no response.

Perhaps the point is that the wrong test IPv4 indicated - he took the first one that came across, Yandex. There was another problem with the fact that during installation it was not possible to create a test file, which I think does not matter.

Answer 1

The same nonsense. I thought there were problems in itables and firewall, but no. Turned them off completely. Installed on VestaCP on Webuzo and just LAMP. The site starts up, but the tests do not work. Even host.
