Machine Deverified on Vast.ai? It Might Be a Sync Issue

Your machine shows "deverified" or throws port errors, but renters are on it right now and their jobs are running fine. That contradiction is not in your head. Hosts in the GPU Autopilot community have hit cases where the private host view and the public listing show different verification states, and the fix was not on their network at all. Before you tear your router apart, learn to tell a real failure from a stale status.

Why a working machine can show as deverified

Vast.ai keeps two views of your machine: the one you see on your host dashboard, and the one renters see on the public listing. In normal operation they agree. But the state you see is propagated and cached on the marketplace side, and those two views can fall out of sync. When that happens, one side shows verified while the other shows deverified or a port error, and no amount of rebooting or firewall tweaking on your end changes anything, because nothing on your end is broken.

The trap is that a sync glitch and a genuine network failure look identical at first glance. So the job is to collect evidence, layer by layer, until you can say with confidence which one you have.

First, rule out a real failure on your side

Work through these checks in order, on the machine itself:

1Confirm your services are healthy. Active rentals still running is a strong signal, but verify it: docker ps should show renter containers up, and nvidia-smi should show their processes on the GPUs.
2
Validate SSH and the assigned ports locally. From the machine:
```
ss -tlnp | grep -E ':(22|40000)'
nc -zv 127.0.0.1 40000
```
Substitute your real assigned range. A local success means the services are bound and answering.
3Test the same ports from outside your network: a phone on mobile data, or a VPS. nmap -Pn -p 40000-40100 YOUR_PUBLIC_IP reporting the ports open means the whole path works. The full outward-facing procedure is in our port not listening diagnosis guide.
4
Confirm probe traffic actually reaches the host. Run tcpdump on the machine while you (or the marketplace) test the port:
```
sudo tcpdump -ni any 'tcp portrange 40000-40100'
```
Incoming SYN packets showing up here prove the internet can reach your machine on those ports.

If any of these steps fails, you have a real problem and the fix lives in networking, not in verification. Follow the port forwarding guide to repair the path first.

Compare the private view against the public listing

If everything above passes, gather the second half of the evidence. Open your host dashboard and note exactly what it says about the machine: verification state, port status, reachability. Then look at the machine from the renter side, on the public search listing, and note what that view says. Do this within a few minutes of your network tests so the evidence lines up in time.

Both views say deverified, network tests pass: likely a stale probe result. Give it a couple of hours; probes rerun on their own.
The two views disagree: this is the sync issue. Your machine is fine; the marketplace's two views of it have diverged.
Both views say deverified, network tests fail: a real fault. Back to the network layer.

Contact Vast support with both results

When the private and public views disagree, this is a support ticket, not a home networking project. Contact Vast.ai support through the host portal and give them both halves of your evidence: the passing external port test with the tcpdump confirmation, and the two contradicting dashboard states with timestamps. A ticket that arrives with that evidence gets resolved much faster than "my machine says deverified, please help."

Never share your API key

Your Vast.ai API key does not belong in a support ticket, a Discord message, a screenshot, or a pastebin. Support never needs it, and anyone who has it can act on your account. If a key has leaked, rotate it immediately in your Vast.ai account settings.

Unlisting and relisting: only with support's blessing

A known workaround for the sync issue is to unlist the machine and relist it, which forces the marketplace to rebuild its view of the machine. Treat this as a last resort with two hard rules:

Only do it if support approves. Support can see the marketplace side and will tell you whether a relist will retrigger synchronization or just cost you queue position for nothing.
Never unlist a machine with active rentals. Unlisting kills your renters' jobs, tanks your reliability score, and turns a cosmetic status glitch into a real revenue problem that follows you for months.

This is field experience from hosts who have been through it, not official Vast.ai policy, so let support have the final word on your specific case.

Know the difference, save the weekend

The whole game here is separating "my machine is broken" from "the marketplace's picture of my machine is stale." The first is fixed with cables, configs, and firewall rules. The second is fixed with evidence and a support ticket. Hosts who cannot tell them apart burn weekends rebuilding networks that were never broken.

If your machine is not just misreported but has actually dropped off the marketplace, switch playbooks and run the 10-minute offline checklist to find the real cause fast.
