Hi there,
new to TrueNAS and many of the concepts involved here. I recently used an old laptop as a home server. It runs Proxmox. I have a virtyal machine for TrueNAS scale. This worked fine for me for a few weeks.
Recently, I can no longer access the TrueNAS web interface from my PC. Via proxmox, TrueNAS VM console, I can see TrueNAS is working (tried rebooting): provided the IP address and the 9 configuration options.
Using this IP address in my browser says “This site can’t be reached.” I presume this is a network/security issue on my PC because I tried the following:
I can see the IP address via my router.
I can access the web interface via browser on my phone.
A ping to the the TN IP via cmd prompt on my PC fails.
I tried different browsers - no success.
I don’t have the first clue about troubleshooting what setting I may have changed since this was working.
I apppreciate any help this community can provide.
Thank you!
This 100% sounds like a network issue, not a truenas issue, if your router can see it and phone can access okay.
Check your PC isn’t set to a static IP that has no route availability to the truenas, if your PC is connected to a switch that is managed, make sure the vlan is allowed to pass through if you’re using a separate vlan for the truenas.
Is the PC using same wifi the phone is using, or is using ethernet?
Since I’m an amateur, I’m going to need more specific questions than “what network settings does the PC have?” because I don’y know how to answer that.
The PC is connected via ethernet directly into my router (wifi for phone).
I don’t know how to check that “PC isn’t set to a static IP that has no route availability to the truenas.”
If it’s helpful, I have other VMs in proxmox that I can access just fine with my PC (HomeAssistantOS, and Ubuntu running Jellyfin). Does this point to a specific port issue?
You’d need to go into network settings of your computer, then look to see if you have a static IP set or a DHCP set, however if you’re not sure how to reach this for whatever operating system you’re using, unlikely it’s set to a static and just using DHCP.
Sounds like might be a port issue then, are you sure you’re going to the correct port for the TrueNAS UI? Default for HTTPS is 443
So in your browser you’d type: IP:Port for example 192.168.1.10:443 and that should take you straight to it
However if you’re not able to ping the IP itself, then probably not a port issue directly. You’d need to review how you have your network setup, or even how you have your proxmox setup to make sure no funny settings etc etc
WARNING !
While you are trying to fix your network issue, please do not store any important data on the Truenas VM. By that i mean data, that you dont have backups from and you dont wanna lose.
The way you setup Truenas as a VM on a Laptop is very likely gonna cause data loss sooner or later.
Correct, browser should auto fill 443 on HTTPS connection by default.
That bit I’m less sure on, I don’t use proxmox so I won’t be able to help much there, someone else might know or could ask on a proxmox forum, probably a good shout as might point you in the right direction for the networking side.
However because you can access it via your phone, it might be more a local issue/router issue than just a proxmox issue. When in doubt, start at the very basics and work your way up; so start at the router and go through it to make sure it’s setup correctly - if you’ve got a spare one, maybe test with that as well to hard exclude the current router from your diagnostics.
Disable it and find out I guess, if you got a public firewall set on a windows device, good chance it will block HTTPS connections as I assume you don’t have a proper SSL Cert for it.
But it shouldn’t block a ping, but might, windows is windows. Have a go
I unplugged my router from the modem and then disabled all firewalls and antivirus software I could find. Still no dice.
I continued messing around today. A few things of note:
My proxmox server has 4 VMs. 3 of them work fine only the TN one is unavailable. From my PC I can ping all 3 but not TN. From the TN VM, I CAN ping successfully the 3 working VMs but not my PC.
Unlike what I said yesterday, I cannot access TN via my phone. I don’t think anything changed… I struggle to explain this… maybe yesterday it was in cache on my phone? Anyway, I cannot ping my phone via TN machine either.
Also posted my issue on the proxmox server… to my simple mind, it seems like it would either have to be a port issue on the network (assuming the TN VM uses different ports than the working VMs) or a network setting on the VM…
