Twitch: "Streaming Service Unreachable" error
Our development is aware of the issue and is currently looking to get this resolved in our next release of Gameshow 4.5. We are hoping to make this available very soon to get you back up and running.
In the meantime, we have a workaround: create a new template BUT skip the output setup by selecting YouTube Gaming, then Next, and skip the authentication. Once you have created your workflow, go into your output settings and then setup your Twitch account/event creation.
We apologize for the inconvenience and will notify you when version 4.5 is available to resolve this issue.
