                      Hi @tyler.boyette, thanks for your message. I'm sorry you're having problems with connectivity. I've reviewed the logs you provided, and everything looks normal, so we'll need to investigate this.

                      Your TinyPilot device has a working Internet connection, as it can upload debug logs, so the ping failures could be due to filtering. The other two error messages relate to the security credentials on your TinyPilot device but don't point to a cause.

                      Can you please check that outbound connections from your TinyPilot device aren't being blocked on the network? Can you please also let me know if you made any changes, such as installing updates, to your TinyPilot device recently?

                          I didn't do anything recently. I also tried with factory reset and tried to install tailscale but it's showing same error

                          curl -fsSL https://tailscale.com/install.sh | sh
                          curl: (60) SSL certificate problem: unable to get local issuer certificate
                          More details here: https://curl.se/docs/sslcerts.html

                          curl failed to verify the legitimacy of the server and therefore could not
                          establish a secure connection to it. To learn more about this situation and
                          how to fix it, please visit the web page mentioned above.

                              @Christopher78 I contacted the tailscale support team and got this message

                              "Having looked at the information you’ve sent me, it looks like this issue is specific to your Raspberry Pi. Based on the error message, it seems there might be SSL interception happening, which is often caused by a firewall or other security software. Do you have any security software running?"

                              Not sure how i can check for my tinypilot device for this.

                              Thanks

                                Thanks for sharing those updates!

                                By default, we don't install any security software on a TinyPilot device that affects Tailscale. However, you can install third-party software over SSH, so if you or anyone with access to your TinyPilot device has installed third-party software, that could be the cause. It's also plausible that one or more networks you use are filtering connections.

                                A factory reset would ensure that your TinyPilot device has no third-party software installed and its filesystem is undamaged. If, after the reset, you install Tailscale, and it works, then the problem is resolved. If the issue persists, you'll know it is due to a network issue.

                                  Hi Charles, I resolved the issue by fixing my wifi. And it's working now.

                                  Thanks for your all help

                                    Thanks for letting me know; I'm pleased it's working! If you're open to sharing the details, I'd appreciate it, as this was an issue we'd not seen before.
