Assuming this was a "private channel" not accessible from the Roku streaming store:
Effective Feb 23, 2022 Roku has discontinued support for ALL uncertified (often called "private") channels. This has nothing to do with the content of the discontinued channels (despite what some of their developers may tell you). It is a removal of ALL channels not certified by Roku and part of the "Streaming channel" access.
The entire non-certified channel system is being replaced by a new system using a new Independent Development Kit (IDK).
From Roku announcement for developers from October 2021:
"Sunsetting non-certified channels
With the release of the IDK and beta channels, Roku will remove non-certified channels from the platform by March 2022. The Roku IDK and beta channel feature will facilitate broader innovation, improve beta testing, and offer a better development experience and a more standardized development process across streaming platforms."
