I recently updated PiHole and ever since then the web interface reports FTL is offline. I get lost connection to API across the top where the graphs are. I've tried uninstalling, reinstalling, switching over to the dev channel. I found a few commands to run after the uninstall. Any help would be greatly appreciated.

Run `pihole -d` for a debug token.

You can also run `sudo service pihole-FTL restart`

What's the output of these commands?

```auto

sudo service dnsmasq status
sudo service pihole-FTL status

I see from your debug log that your system it running on `CentOS Linux 7 (Core)` which is a system we officially support. Apparently, you found some CentOS speciality I have not encountered during testing. A quick searching through the web found several similar issues with other software. You can play e.g. with this here:

[https://serverfault.com/a/667794](https://serverfault.com/a/667794)

Let us know if it helps for your issue and we will incorporate it for the next release!

Here is my startup script for pihole-FTL. I'm confused on where I should add the RETVAL=0. I tried a few places but I still get **/etc/init.d/pihole-FTL: line 68: status: command not found**. Any help would be greatly appreciated. Thanks!

I was thinking that you might want to try something like this:

Add

```plaintext
. /etc/init.d/functions
RETVAL=0

```

in between

```plaintext
### END INIT INFO

```

and

```plaintext
FTLUSER=pihole

```

I installed `CentOS` + `Pi-hole` on one of my testing systems and have been able to reproduce your particular issue:

```plaintext
[root@vultr ~]# service pihole-FTL status
/etc/init.d/pihole-FTL: line 69: status: command not found

```

after adding the lines I suggested in me previous post, it works as expected:

Okay, does the `sudo service pihole-FTL status` command show you that `FTL` is active?  
If yes, please try to connect to `FTL` locally using `telnet`:

```auto
telnet 127.0.0.1 4711

```

If that works, try to get some statistics by typing

```auto
>stats

```

and hitting Return.

To quit you type `>quit` + Return.

JFYI I solved it by removing the whole container and installing it on new one, this time Debian one, since the installer failed on Ubuntu containers. Works fine, though I had to connect via ssh to the machine, otherwise I couldnt operate the installer.
