Failed to record. Invalid token

#1

I've been recording on channel 6058 (Bravo through Sling) for a few months with no problems. On one recent scheduled recording I got a failure message:

Failed: could not start stream on channels=[6058]: TVE:invalid token.

Wondering what this is? Log didn't show anything.

Sounds like authentication failed. Are you able to tune the channel live?

#3

Yes. I can tune to it live along with all other channels. It failed on channel 6058 but then recorded it on 6059.
