Can not access Plex Web UI -Connection refused

[Sabot68]

HI All,
Firstly let me say I am an absolute beginner when I comes to TrueNas and anything Linux. Having said that I have installed TrueNAS and created a pool and setup some SMB shares and some user accounts.
I am now trying to get Plex to work, First issue is when installing the plugin it will fail if DHCP is selected, installs fine if NAT is checked. Once installed and a pool mounted I can not get to the web UI via the 'manage' link, get "ERR_CONNECTION_REFUSED" error.

My system is a HP Z820 workstation which is connected to my home network (modem/router)
TrueNAS version is 12.0-U6

34 views and no replies? Did i not supply enough info? I have seen similar posts with no solution.....

 

[Samuel Tai]

Not enough info. First, please provide your network summary. Next, we'll need to see your bridge configuration: ifconfig bridge0.

 

[Sabot68]

HI Samuel,
I entered that command in the system shell and got "interface bridge0 does not exist"
As for my network setup my TrueNAS system is connected to my router via em0 network interface (ip 192.168.0.25\24)
I also have added a Mellanox 10GB nic which I have setup as a direct connection to my desktop, its on a different sub net- 192.168.200.xx
I have installed the Plex plug in as per a how to video on youtube.
I can ping the TrueNAS computer (Hp Z820 workstation) from my desktop.

 

[Samuel Tai]

No, I meant, please provide a screenshot of Network->Network Summary. Given that you've multiple interfaces, that explains the lack of a bridge interface, which is required for the Plex plugin to use DHCP instead of NAT. For your plugin, please provide the output of iocage get all plex.

Hi Samuel,
here is a screen shot of the Network Summery page

As for iocage get all plex, I tried that both from the shell in the left hand pane and its said- jail 'plex' not found!
And from the plex jail shell- iocage: Command not found.

Apologies if this is not what you have asked for, I am a complete beginner when it comes to FreeBSD or any flavour of Linux and TrueNAS

 

[Samuel Tai]

Sorry, try iocage get all Plex | more and also ifconfig -afrom the left-hand pane shell.

 

[Sabot68]

HI, I have uninstalled Plex and now I can not get it installed again

and here is what i get from the ifconfig command:

OK, so the problem is you do have a bridge0 interface, but neither em0 nor mlxen0 are bound to it, so that's why DHCP fails, since jails use bridge0.

How is your PC connected? Is it also connected to the 192.168.0.0/24 subnet and to the 192.168.200.0/24 subnet? I recall you have a direct 10G connection to your TrueNAS server.

 

[Sabot68]

So my desktop and Truenas are connected to my network by 1gb ethernet, Truenas box static ip 192.168.0.25 and my desktop DHCP 192.168.0.XX.
10Gb connection is a direct connection between truenas 192.168.200.1 and Desktop 192.168.200.2

 

[Samuel Tai]

OK, that's what I thought, but I needed confirmation. The basic problem is the 10G link between your PC and your TrueNAS server doesn't have DHCP, only the 1G link. With a single NIC, the plugin workflow knows to create a bridge, and assign the single NIC to it for jail DHCP networking. With 2 NICs, the workflow bails, since it doesn't know the network topology. To overcome this please:

1. Delete the current bridge0 interface by running from the shell: ifconfig bridge0 destroy.
2. Next, create a new bridge0 interface under Network->Interfaces, and click the Add button. Set the type to Bridge, the name to bridge0, and under Bridge members, select your em0 interface. Click Apply to create the bridge0 interface.

Now, you can create your Plex plugin using DHCP. The workflow will use any pre-existing bridge0 interface.

Thanks, I will try that when i get back home, the Hp z820 workstation that i am running truenas on does have 2 nics on board, but I am only using one of them (beside the 10gb add in card)

 

[Sabot68]

ok so I tried the ifconfig destroy bridge0 command and the system says bridge0 did not exist, continued with your instructions, created a bridge on emo, continued to install plex plug in and it stalls on the installing plex dialogue box

here is a screen grab of my dashboard showing link states...

Thanks for you help so far.

 

[Sabot68]

update, not sure what i changed, i didn't think i had changed anything but now the install is not stalling but back to where i was earlier, gets to about 50% then a dhcp error:

Dont know how to access the jail logs.

 

[Samuel Tai]

Are you using a 0 (zero) or O (capital O) in the bridge0 interface name?

 

[Sabot68]

A Zero

 

[Samuel Tai]

OK, this is kind of drastic, but pull your Mellanox. Also delete the bridge0 interface you created. If there are any other bridge interfaces showing in ifconfig -a, then run ifconfig <bridge interface> destroy. Once your system is running on just em0, go ahead and create your plugin. Once the plugin is up and running, reinstall your Mellanox.

 

[Sabot68]

Hi Samuel,
No thats not too drastic, I was thinking of doing a complete reinstall, this current install is only a test setup so there is no crucial data at risk,
I will pull the mellanox card when I get home in about an hour

 

[Sabot68]

Hi Samuel, Not sure what I'm doing wrong here, i am entering the ifconfig commands as you instruct but the bridge and interfaces do not disappear, they are still visible in the dashboard, I have removed the mellanox card

 

[Sabot68]

Could user accounts be an issue here, could I have screwed up an ACL that is somehow stuffing up the plex install? the plugin has installed before and I have not been able to get to the management web ui.....
