UI.com / UniFi Network Application connectivity problem - STUN or other traffic blocked?

tunes_in_my_head · February 2, 2025, 4:13pm

When I first used this Add-on, I could monitor the status and make changes to my switches and APs both locally via the IP of my HA server and from ui.com. In the last couple months (at least when I became aware of the issue), ui.com just times out and a toast notification says “connecting to site is taking longer than expected”.

There seem to be numerous threads about the issue on Reddit and I think I have tried all the “fixes” to no avail.

I have noticed the log repeatedly has these lines:
:0 Permanent error code on allocate request: 420 - . This was after receiving a valid nonce
:0 TURN instance failed: TURN id: 3; fd: 262 0.0.0.0:58564 → 141.101.90.1:3478 (all_interfaces) DTLS id:

Thought it was a firewall / port forward issue but either I don’t have the rule(s) configured correctly or that isn’t the problem.

Everything else with HA is working fine - VPN, integrations, remote access, reverse proxy, DNS, etc.

For UniFi gear I have a USG-3P a USW-Pro-48-PoE and some UAC-AP-Pro access points. All VLANs have been in place for over a year and the traffic for all devices and subnets is working as desired / expected. I have the latest application release [9.0.108] and current firmware on all devices.

My HA server and the UniFi gear reside on the same VLAN, BTW.

Core 2025.1.4
Supervisor 2024.12.3
Operating System 14.2
Frontend 20250109.2

Did you ever get to the bottom of this? Got the same issue

I have not looked back into this for quite some time. I decided it is more a nuisance, and the additional time spent troubleshooting would not be worthwhile.

i’m with the same log timeout and wish to know what is the reason, solve if possible

another question, di you have a way to manage rhe port of the switch with HA (ha-plugin) i don’t see any entry for that ?

I have installed latest HA OS with Unifi Network application addon, everything is fine except I can’t connect through unifi cloud to application which times out and application restarts itself with very similar errors. I used access to unifi network application through mobile app which is not possible even in local network because of this issue. Any advice?
