Access via cloudflare not working

[meszolym]

I have a Cloudflare tunnel set up on one of my proxmox VM-s. It works fine with everything except proxmox. I have proxmox.mydomain.net set to my proxmox servers ip (let's say it's 192.168.0.2:8006), over HTTPS, no TLS verify set to true, TLS timeout set to 20 sec, disable chunk encoding set to true.

I can log in, it does reject bad passwords. I type in the right pass, the right 2FA code, and it logs in, but doesn't show my stuff (nodes, VM-s, etc). All there is is a datacenter named ASD with nothing in it. After a couple of seconds it throws me out with no error. If I try to log in again, it says: "Connection error - server offline?".

Anybody got any suggestions with this error?

Turns out the config works, the problem is with the application security I used.

Had to disable binding cookie.

I have the same issue. Created a subdomain on Cloudflare pointing to my local Proxmox instance https://192.168.1.162:8006 but can't get it to work. Tested with other Proxmox applications such as pihole and that works without issues. How did you get it to work ?

Binding cookie ? How/What ?

Binding Cookie is on your Cloudflare Access Applications if you made one, should be disabled by default tho

Hi, i have a similar issue i have a domain.com domain name witch redirect to duckdns.org.
And it "works" except it does not..

What i mean is i can login and so but my cluster does not show up for some reason.
I get the same massage:

Connection error - server offline?

Console out puts this:

Failed to load resource: the server responded with a status of 401 ()

and it is maybe connected with

/api2/extjs/cluster/options?_dc=1709145420365

If i use the duckdns.org domain to access it it works as intended,
but if i use my domain.com domain (witch is only directing to the duckdns.org domain) than it does not work as you can see blow:

Hi,
I have installed Clould flare tunnel on my Raspberry Pi at home network
also have proxmox server which is running some VM (Adguard, TrueNAS, Ununtu etc)

with the Help of clouldflare tunnel on RaspberryPi, I am able to access VM GUI (same VM's installed in Proxmox)
but I am facing same issue, Not able to access Proxmox GUI via clouldflare

tried to see cookies thing, but unable to figure out how to setup

The fix that worked for me (PM v8.2.4,Cloudflare v2024.10.0) was ensuring these three Cloudflare options were selected in the Tunnel Hostname configuration:
http2Origin
noTLSVerify
disableChunkedEncoding (I think this is main culprit, but these settings worked for me)

they are found in Cloudflare>Networks>Tunnels>(tunnel name>little three dots>configure)>Public Hostname tab>(little three dots next to Hostname>edit)> Additional Application Settings>(TLS & HTTP settings tabs, respectively)

happy trails,

G

Just wanted to say thanks! This seems to be a new issue, most likely with the latest cloudflared. We were running an old cloudflared from last year and just updated it over the weekend when this started happening.

For anyone else that ends up here. Here are the settings:
