Can't add Sling TV to TVE - "Context Canceled" error

[mxplea10]

Trying to access ESPN via Channels TVE, I deleted Sling TV from Channels. Following TV Everywhere Availability (Channels Support - TV Everywhere Availability), I verified that I could access ESPN via the web browser. I rescanned the Sling TV channels several times and after that didn't work, I deleted the Sling TV source. When I tried adding Sling TV back to TVE, I got the error "Context Canceled". I updated Channels to the latest version and still get the error "Context Canceled". The Channels DVR app is running on a WD My Cloud PR4100.

I read another post where someone was getting this error with Xfinity and was told to disable auto authentication. I checked my Sling TV account and can't find where auto authentication is set. What can I do to add Sling TV back to Channels DVR and get all channels available? The logs are below.

Do you have chrome/chromium updated on the server?

Hello, thanks for the input. I don't think my server is running Chrome but I'll research it. I verify that the firmware on the WD MY Cloud PR4100 is updated. The desktop Chrome browser wasn't the latest version and has been updated. The Chrome error didn't appear again but I'm still getting the "Context Canceled" error message and can't add Sling TV. I'll continue troubleshooting.

Chrome is supplied inside the WD MyCloud package install. https://getchannels.com/dvr-server/#wdmycloud

Most likely v114

Not sure if that older version is causing issues, but the CDVR docker install currently uses v120

Could just be the Sling auth servers are having another bad day.

I agree with what chDVRuser said. Go to Support and Troubleshooting and see if at a minimum version 114 for Chrome. If there is an update you should see a click to update to a newer version. Your desktop version of chrome generally doesn't matter.

That was it! Chrome was corrupted. I went to Support and, then, Troubleshooting. It's good to know this feature exist. Sling TV loaded without issue after updating Chrome. Thanks you both for your help.
