Can access tinypilot via tailscale through browser BUT NOT on LAN

@manimgoindowndown - This unfortunately is not enough information for us to help you.

Diagnosing home networking issues is out of scope for what we can support. If you share a map of your network topology and the internal IP addresses of your devices (e.g., "TinyPilot is at 10.0.0.110, Desktop is at 10.0.0.111, ..."), we can let you know if we see issues in the setup, but the information provided so far does not give us enough information to understand the network.

To summarize, in order for us to help, we'll need:

• A map or detailed description of your network topology
• IP addresses of the TinyPilot, target desktop, and client laptop (full IPs, not just the last octet)

It’s true that client isolation is most commonly used with WiFi but it can also apply to devices attached over Ethernet. Client isolation will normally allow a device to talk to the router or gateway (and, usually, all the way through to the Internet) so it would match the scenario you are seeing. I appreciate it might seem unlikely but it’d be good to rule it out if possible.

Could you please provide the full local IP addresses and, if possible, a detailed diagram of your home network? This is so we can see if they are in the same logical network. This is important because, for example, a device with an IP of 192.168.0.1 would not be able to talk to a device with an IP of 192.168.1.1 (assuming they are both using a 255.255.255.0 subnet mask) without an intermediary router.
