Hi @milselarch welcome to the community and to OpenZiti! Sorry for the delay, it's a busy time for us all here at with the OpenZiti project and within NetFoundry on the whole. When an issue comes in that takes a bit of time to try to understand, it's harder for us to reply quickly. What zrok controller/frontend versions are you running and what versions of OpenZiti are you running? You're just trying to get the sample to run, right? ---

Hi @TheLumberjack thanks for getting back to me Yeah i am just trying to get the sample to run. The version of zrok im using is 1.1.11, I don’t think I am running any zrok controller / frontend, or OpenZiti, cause I was expecting to connect to the zrok servers hosted at my [myzrok.io](http://myzrok.io) rather than self-hosting? ---

I don't believe the python SDK for v1.1 is functional. If possible, have a look at the python sdk for v2. It's significantly improved.
