Hello! I recently replaced my motherboard, and now my previously working Tailscale node is no longer connecting. I looked through the documentation and found that the issue was caused by changing the TPM. In my environment, I've had to change it several times for testing, so I created a Rust utility that clears and initializes TPM-related files. I hope this helps anyone who's had the same issue! Caution: System files C:\ProgramData\Tailscale C:\Users%USERNAME%\AppData\Local\Tailscale, /var/lib/tailscale/tailscaled.state Administrator privileges are required because this deletes data! You can run it using Rust Cargo or by downloading a pre-built Release file. :) Since my native language isn't English, please forgive any awkwardness!
