I’m trying to access a Perspective project remotely. I have installed and configured Tailscale on the server and the remote client. When the VPN connection is up, I can use RDP to remotely connect to the server from the client. I can also use the VPN-assigned IP in file explorer to access the file system on the server.
However, when I launch a browser and use the VPN-assigned IP and port 8043, all I get is a line of characters on a blank page.
I reached out to Tailscale support and this their response:
" That the browser managed to connect to [100.xxx.xxx.xxx], did not timeout nor get a connection error, implies that the connection across the Tailscale network did work. My guess would be that the application listening on port 8043 has been configured to only allow connections from certain addresses, like probably the loopback address and the local LAN.
If it is interpreting the connection from a 100.x.y.z Tailscale client as something from the Internet, the weird characters may be the attempt to send an error like 403 (and perhaps the error page is broken)."
I don’t remember white-listing IPs on the Gateway. Other computers on the same network can access the SCADA without any issues.
