Tailscale failed to get device binding link

SOLVED: SSH into the router then run tailscale status , the binding link should be spit out via the terminal. Copy and paste it into (or retype it into) your browser to authenticate. The Tailscale admin panel should show that the device is now connected. Credit to HarvsG for this fix.

OP: Just got the GL-A1300. The software version is OpenWrt 21.02.2 r16495-bf0c965af0, Kernel Version 5.4.179

When I enable Tailscale, i get a message that the Tailscale service is enabled, but the device is not bound yet. Please bind this device to your Tailscale account using The Device Bind Link (a clickable link). When I click the link, I get an error Tailscale failed to get device binding link.

Any ideas on next steps?

Can you tell me the firmware version of your GL-A1300?

Thank you. Succesfully accomplished in FW 4.3.7 Release 4 in AR750S Slate.
