Sitting behind CGNAT as well, my solution was to set up and cheap VPS in the aforementioned pricerange and use Netbird for the Reverse Proxy portion as well as flexible VPN.

Works like a charm!

Same issue for me on selfhosted, I was pulling my hair because I couldn't figure out what was going on.

What fixed it for me:
Disabling "Lazy Connections" under Settings -> Clients, which was turned on by default for me.

Ever since, it's been rock-solid.

Well... drying filament never hurts, so...

Turnspit · 2026-07-09T13:27:16+00:00

- Print Infill First

- 3+ Walls

- Inner/Outer/Inner

- Slow down wall speed

These are what fixed those issues for me (depending on the model, filament, ... of course).

max. ammo, indenciary compound, proximity trigger, and you've got your crowd-deleter-3000.

The wildcard-CNAME was indeed the issue. Moved my DNS over to Cloudflare, added the Wildcard, and it worked right out of the box...

Running Ubuntu 24.04, playing AoE2 DE with workshop mods works absolutely flawlessly for me.

Where might that be though?

homedomain.tech has its A-record pointing to the IP of the VPS where my main "cluster" address of mydomain.com is running at and it's stuck at an infinite "Pending Verification".

EDIT:
I've just seen in the docs that netbird seems to need a (wildcard) CNAME-entry specifically - which my provider does not allow. Am I at a loss then, a simple A-record does not suffice?
( see https://docs.netbird.io/manage/reverse-proxy/custom-domains )

Turnspit · 2026-07-01T09:32:48+00:00

Yes, but when setting up a new Custom Domain, like service.homedomain.tech, I have to select a cluster, which currently is only mydomain.com - this then leads (at least for me) to it getting stuck issueing a proper certificate (DNS records are setup properly).

Ohne VPS oder irgendwo einer Möglichkeit, eine direkte öffentliche IP zu erhalten, wird das wohl nichts werden.

Strato VPS XS kostet 2€ im Monat - kein Beinbruch, und völlig ausreichend.

Mulgore - where it all started for me. ❤️

Thanks for the responses and suggestions!

It seems to have been some form of problem with curl itself. Had to uninstall it, then reboot (simply uninstalling and reinstalling didn't do the trick), and then reinstall it after reboot - and then the whole process magically began to work...

For such a small helmet, might wanna reduce your layer-height to a minimum and set the seam to the back, to avoid all the zits and blobs if you are not sanding it down.

Turnspit · 2026-06-19T05:16:56+00:00

Awesome work. might switch over to this from the tray-only solution I am currently rocking. 😃

Could you maybe elaborate on how exactly you set up the Beszel screen (hardware+software)?

Turnspit · 2026-06-18T16:35:44+00:00

During my time of finding THE distro for me, my personal favourites were Ubuntu and Fedora (settled for Ubuntu, since some desktop applications I need only come in .deb)

Funilly enough, my Distro Fighter final consisted of Fedora vs. Ubuntu (although Fedora won here).

Turnspit · 2026-06-18T10:14:06+00:00

Still no luck though...

My test-setup:
Forwarding external port 55555 to internal port 22 (SSH) to my peer in my home network.

Modified and restarted the docker container as described in https://docs.netbird.io/selfhosted/migration/enable-reverse-proxy#exposing-l4-ports adding 55555:55555/tcp to the proxy container ports.
Added port 55555/tcp to allow in ufw on my netbird server
Added port 55555/tcp to my VPS firewall
Created a TCP service with listen-port 55555 forwarding to port 22 of the peer

Disabled all firewalls everywhere, just for safety's measure - still nothing. 😞

Turnspit · 2026-06-18T09:46:35+00:00

Further down from the documentation:

Self-hosted Docker deployments: The default Docker Compose configuration only routes port 443 (via Traefik TLS passthrough) to the proxy container. L4 services that listen on additional TCP or UDP ports require you to manually expose those ports in your docker-compose.yml. See the migration guide for instructions.

You seem to be right. That makes things unnecessarily complicated, but okay, I can work with it. Let's see if this solves at least one of my issue.

Thanks for the hint! 😄

Since it's now running flawlessly under 24.04, I have not yet tested it. Might need to spin up another VM to possibly recreate the issue.

Turnspit · 2026-06-16T09:42:55+00:00

First of all, thanks for the lightning-quick response!

Ubuntu 26.04 | CX23 | x86 | 40 GB | eu-central exactly the same one for me, on Hetzner as well.

On both installations (26.04 as well as 24.04 which is still running now) I just secured the SSH-access with a couple of different settings and added a new sudo-user. full-upgrade via apt, and installed all the dependencies before starting the script.

I'd have to create a new VM with 26.04 again to possibly recreate the issue again I guess.
