zrok v1.0.x uses a different API endpoint than v0.4.x. v0.4.x used the endpoint https://api.zrok.io, and v1.0.x uses the endpoint https://api-v1.zrok.io. To allow ease of migration, we're running both v0.4.x and v1.0.x in parallel in production.
zrok v1.0.0 includes a new command zrok rebase, which is used to update an existing environment (created using zrok enable) to point to a different API endpoint (the API endpoint is stored in the environment).
To update your environment to the new endpoint, you'll want to execute the docker equivalent of the command:
$ zrok rebase apiEndpoint https://api-v1.zrok.io
