You open AnyDesk and instead of your device list you get the red banner: “Not connected to the AnyDesk network” or “not connected to server”. Nothing dials, nothing answers. Here are the fixes that actually resolve it, in the order worth trying — and an honest plan B if none of them stick.
1. Check AnyDesk’s own status first
Before touching your machine, rule out theirs: search for “AnyDesk status page” and check for an outage notice, or look at their social accounts. If the service is down, no local fix will help — that’s the moment to have a fallback tool installed (more on that below).
2. Restart the AnyDesk service, not just the app
Closing the window doesn’t restart AnyDesk’s background service. Press Win+R, run services.msc, find AnyDesk Service, right-click → Restart. (Or from an elevated terminal: net stop AnyDesk && net start AnyDesk.) This alone clears a surprising share of cases.
3. Let it through the firewall and antivirus
In Windows Security → Firewall & network protection → Allow an app through firewall, confirm AnyDesk is allowed on private networks. Third-party antivirus suites are a frequent culprit — check their logs for blocked connections and whitelist AnyDesk if you trust it.
4. Try another network (the fastest diagnosis there is)
Hotspot your phone and connect through it. If AnyDesk comes alive, your problem is the network, not the PC: strict office/hotel firewalls, DNS filtering, or an ISP block. On managed networks, AnyDesk’s ports are commonly filtered on purpose — ask IT, or accept that this network won’t carry it.
5. Flush DNS and reset the network stack
From an elevated terminal, run ipconfig /flushdns, then netsh winsock reset, and reboot. Stale DNS or a corrupted socket layer can strand exactly one app while the browser still works.
6. Check for a proxy or VPN in the way
If Windows is configured to use a proxy (Settings → Network → Proxy) or a VPN is active, AnyDesk may be unable to reach its network even though websites load. Disable them temporarily and retry; if that fixes it, configure the proxy inside AnyDesk’s settings instead.
7. Reinstall — or accept that you’re geo-blocked
A clean reinstall (remove, reboot, install the current version) fixes corrupted installs. But if you are connecting from a sanctioned region — Iran being the common case — the truth is simpler and harder: AnyDesk blocks these regions at the network level. No local setting changes that, and VPN workarounds break the moment the VPN does.
The plan B worth having installed
Every fix above shares a weakness: when the tool’s network is down, blocked or filtered, you’re locked out at the worst possible moment — usually mid-rescue of someone else’s PC. The resilient setup is having a second, independent tool already on both machines.
DoorDast is a free remote desktop for Windows built for exactly the failure modes above: it needs no VPN and no port forwarding, automatically falls back to a firewall-friendly connection on strict networks, isn’t region-blocked, and every session is end-to-end encrypted — private even from us. Install takes under a minute, guests can even watch from a browser with nothing installed, and the price is zero, permanently.
If AnyDesk is working for you, keep it — genuinely. But put DoorDast on the machines you care about before the next red banner, and “not connected to server” becomes a shrug instead of an emergency. Curious how they compare feature-for-feature? DoorDast vs AnyDesk.
