Status offline on Centos 7, pihole works

Help Community Help
1

The issue I am facing:
on the web i/f status always says: 'Offline' - though pihole works as expected
if I disable via admin page, then enable, says 'Active', when page refreshes, says again 'Offline'
looking on this forum, found similar issue, with such solution:

ls -l /usr/bin/sudo

---s--x--x. 1 root root 151424 Oct 14 23:28 /usr/bin/sudo

did below line, result below

sudo chmod 4755 /usr/bin/sudo

ls -l /usr/bin/sudo

-rwsr-xr-x. 1 root root 151424 Oct 14 23:28 /usr/bin/sudo

but, didn't help

Details about my system:
Centos 7, Apache

I think the problem is related to running an unsupported web server.

What device are you running Pi-hole on? We only check in two places for temp sensors (there are many!) and due to a bug the above error message gets printed. This has been fixed in the next release (the error message, not the temp sensor lookup).

What is the output of

sudo pihole status web

The reply is correct, so it is likely an permission issue with your apache.

We do look for sensors in
