check_disk issues with a sshfs mount

Hello guys,

Im having an issue with check_disk with a sshfs mount, Im getting the following,

DISK CRITICAL - /new is not accessible: Permission denied

Im using NRPE with check_disk plugin.

Does anyone know what could it be causing this? “df -h” shows the mount correctly and I can access it without issues as well.
/dev/fuse is owned by root:fuse and fuse group contains nagios user on it.
/dev/fuse is also readable/writable by both.

Thank you in advance.
