this is a third-party app, maybe you are missing a library. but I do not see this as a future problem, if I am in your shoes I would google for a solution, if I cannot find it I would just ignore it.

Quick google suggest that you start from here ; https://github.com/phpsysinfo/phpsysinfo/issues/119

Maybe permissions issues, same as it suggested , since if I remember well , you're also using Raspberry Pi. https://www.reddit.com/r/linuxadmin/comments/43fhvv/debian_8_devnull_permission_denied_when_ssh/

Hi, Sorry for the delay but I am traveling for a relative of my family, at the end of his life

The server is a vps on digitalocean (amd64).

I have changed the owner of "/var/www/html/AVideo-Storage/" in www-data to avoid lack of privilege issues.

Investigate the links provided and other research I found this bug that sound interesting: https://bugs.php.net/bug.php?id=79060

is_readable() tells you whether you have "r" permissions on the path (which you clearly do, as the fopen is successful). It does not tell you whether actually reading from the FD will be successful. (A simple example is a directory -- on Linux these will fopen fine, but fail reading with errno 21.)

The behavior of /sys files is determined by the kernel and/or device drivers. This particular file happens to reject reads with errno 22.

That's just how things are. If you try to "cat /sys/class/net/lo/speed" you'll get exactly the same result._

But I don't understand what I have to do in order to fix it
