panic: tls: setSessionTicketExt failed: invalid state

I'm doing multiple http requests with uTLS being set on a transport level.

Recently caught this while doing mass requests, unfortunately no context on the exact server that caused this

It would help if you could provide a minimal example to replicate the error.
