Tailscale cannot connect on Unifi Wifi, but works on hard wired connections

[river pumice]

I can't get tailscale to work on wireless clients on Unifi WiFi networks (3 different locations) while the same clients work fine on the LAN networks of these deployments, as well as over 5G or when I try the WiFi at my work location.

https://tailscale.com/kb/1181/firewalls#unifi-gateways is outdated, but regarless the configs already set up to not block P2P.

The WiFi networks are in the native vlans, and have no firewall rules that would block this traffic.

Any ideas? I see lots of forum posts with no resolution...

Can you generate a bug report from a machine while it's unable to connect? That could give us some context.

Will do when I get home in a couple of hours.

Well, apparently that is not possible, unless logs are retained for previous sessions? I could connect on 5G and capture it then.
When I try to connect from an iOS device it just gets stuck here. I’ll try from MacOS shortly

Switched to 5G connected and created the report: BUG-2974005b58f5d3b5f10d06fc43cad91d61a5bffd3445f86aea1c9d51c1030e86-20250827213250Z-3dbede1a89abfebb

Thanks, looking at that telemetry, it's a lot of connection timeouts. This sounds like a firewall issue - blocking the peer traffic, but allowing the logs to get through to the Tailscale servers. I'm out for the evening, but hopefully that can get you on the right path.
