Looks like there may be a CDN/linking error. Other services are not showing Adam-12 as available via Roku Channel so not too sure on this one. (Roku Search results are the only indicator that it is available on the Roku Channel. Other sources showing available only on Freevee).
Adam-12 is playing correctly on the free channel/app Freevee that you can install on your Roku device.
