I guess the error message could be better, but TLS is not supported with DeviceScript on Pico-W, please see https://microsoft.github.io/devicescript/devices#implementation-status

PRs are welcome!

Thank you for your reply.

It seems that pico does not support TLS.
Even now, the same error also seems to occur after the second time when using TCP (http) communication.

If I have enough time to make a PR, I'll look into it!
However, I will wait for the new version of DeviceScript for a while!

regards.
