How I fixed my RLC-1000 error (Roku vs Spectrum app)
Ever since I switched out my internet modem with a Spectrum modem I was not able to connect to the Spectrum app on my Roku express.
I kept getting a prompt to login (which I didn't get before) and after trying to login with verified good credentials I got the RLC-1000 error (Connect to Spectrum internet...)
After a great deal of researching, resetting all devices, contacting Spectrum (useless), contacting Roku (non-responsive). I finally figured out the solution.
It appears that my router still had my old cable modem mac address cloned into it. I just had to go into my router configuration and re-clone the new mac address for the new cable modem and the ROKU worked (without even having to login). Hope this helps someone.
