I cant connect to webgui of proxmox instance using my win10 pc even though my ios phone connects just fine.
Router brand: HALNY

I tried:
-turning firewall off
-https and http
-different browsers
-private window in browser
-reboot of pc, router and proxmox server

Is there anything I'm missing?

do you have firewall ON ? maybe your blocked your home IP?
there are firewall in datacenter> firewall
and Node Firewall as well
and then VM Firewall on proxmox

https://pve.proxmox.com/pve-docs/chapter-pve-firewall.html

https://XX.XXX.XXX.XXX:8006
should always be used to login http will not allow you to get to the web gui.

I would try to choose a browser with a vpn to test if your IP is the issue or is blocked.
only thing I can think of.
Sorry hope you get it figured out

continuing on this thread here since you posted another one and i didn't realize :)

hi,

* are you on the same local network as the PVE server?

* just to be sure, are you connecting to the interface like this: https://your.pve.ip.address:8006

* are you able to connect via SSH to your PVE host?

- I am on the same network, both computers are connected to the same router via ethernet cable
- Yes I am connecting to the addres given in the login page visible when turning proxmox (https://your.pve.ip.address:8006), I know the IP is correct becasue on the router page under the IP addres there is the correct MAC
- No, I can't connect to PvE host using this computer (using "ssh root@pve.address" typed into the cmd)
- I can't ping a website set on my pc from proxmox even thought the website works fine on my phone

* have you checked your windows firewall settings as well?
* are you using any antivirus software? (would check the firewall component)
 
okay

okay

* are you using any antivirus software? (would check the firewall component)
- It still doesn't work with windows firewall turned off
- No, I only use windows defender
 
* can you ping your windows machine from the PVE host?

* please check your PVE firewall settings, you can temporarily stop all of them to test if it still doesn't work: pve-firewall stop

beyond that, you could try installing and running tcpdump on your PVE machine and try pinging it from the windows VM to see if the network traffic shows up:
Code:
apt install tcpdump
tcpdump -v icmp

and then ping your PVE host.

- I cant ping a website setup on windows machine
- I still can't connect to the PVE from windows machine after typing pve-firewall stop in the PVE CLI
- After running tcpdump with the command given by you and pinging the PVE host from the windows machine still the requests get timed out on the windows machine BUT on the PVE instance there is
Code:
16:20:00.512740 IP (tos 0x0, ttl 128, id48341, offset 0, flags [none], proto ICMP (1), lenght 60)
 ip.of.windows.machine > example.local: ICMP echo request, id1,seq 491, lenght 40
for every ping (with some numbers changing)
 
"- I am on the same network, both computers are connected to the same router via ethernet cable"

Are you sure that the win10 pc is in the correct/same subnet as the PVE host?
Please check ip addresses and if possible give the PVE host a static ip address.

As said in my last comment I am able to ping the PVE instance from my win10 and get a log on the CLI that I've written above which means they can connect.
PVE has a static IP by default.

Nothing you posted in this thread shows that you are able to communicate/ping the PVE host. The snippet of the log only shows requests, not replies. In fact, you specifically said "I cant ping a website setup on windows machine".

I am going to assume that you don't have your environment on open public network and that you are not working in classified environment.
So please provide a full non-obfuscated output of:
1) PVE: ip a
2) PVE: ip route
3) PVE: sudo apt install net-tools; arp -an
4) Windows : ipconfig
4a) Windows: arp -a
5) Windows: ping 8.8.8.8
6) PVE: ping -c4 8.8.8.8
7) Windows: ping ip.of.proxmox
8) PVE: ping -c4 ip.of.your.router
9) Windows: ping ip.of.your.router
10) PVE: ping windows.ip
11) PVE: iptables -L

P.S. are you sure you dont have a duplicate IP on your network?
1) shutdown PVE
2) Windows: ping ip.of.proxmox

PS. My router DHCP server is set to give IPs in range 192.168.0.100 - 192.168.0.200 and the IP of PVE is 192.168.0.11 and I didn't setup anyhing which means it cant collide with other devices
1 & 2) pinged PVE ip while it was turned off

My router says its static and it's out of dhcp reservation range

@Spirog The output is not in most friendly to follow format, so its easy to lose correlation. The "dynamic" portion that confused you is from Windows side as it sees Proxmox. For windows that ARP entry is dynamic.

@becal the hosts see each other, they know about each other's MAC's (assuming windows MAC is 2c:f0:5d:ad:a3:c6 which you can check via "ipconfig /all". They can talk via router to outside world.
Take the ethernet cable from windows and plug it directly into proxmox and test again. You may need to set you windows to a static IP.

UPDATE:
I found a setting in my router called "IGMP LAN Isolation" that was turned ON, I thought this was the source of the issue but after turining it off nothing changed and the webgui still works fine on the phone, Is it possible that there is some other setting that blocks LAN to LAN connections on a local network in a router? ( I don't think my router supports VLANs as I don't see any page to change the settings for them)

After plugging ethernet directly from windows to PVE and setting windows IP as static and rebooting both computers it works!
(obviously after trying to do it through the router again it doesn't work)
Am I correct in assuming that it has to be a fault of the router since both firewalls were on?

Router didn't have any options to unblock the lan port isloation. I called the ISP got the router replaced with other one and everything works normally. (Brand of the router that didn't work is HALNY)
