Channels DVR Server Troubleshooting
#1

I started getting this Java error today. If you need more information let me know. Here are the versions I'm running.

Channels: 2018.11.20.2224
Windows 8.1 Pro with Media Center

Also tried installing the latest version of Java Version 8 Update 201 but made no difference. This occurs on the Settings tab.

Please refresh the browser after reporting this issue on Channels Community or to [email protected].

Does it show the Check For Update button? Try holding SHIFT and clicking it.

#3

It says Checking... but the screen flashes on and off and the lower settings window text goes blank and then repeats. Nothing happens when I hold the Shift key and try to click on Check for Updates. The button is not showing long enough to click on it.

#4

I did a screen capture of what I see. Do you have a place I can upload the 9MB mov file?

#5

Open powershell and run:

curl -Method Put http://127.0.0.1:8089/updater/check/prerelease

Let me know if that fixes the issue after waiting a few minutes for it to update, then refresh the browser.

#6

Thanks, that worked. I now have version: 2019.02.12.0028

I received a javascript error just now. I'm running version 2018.11.20.2224 on Chrome 71.0.3578.98 and macOS 10.14.2

Here's the error:

Does refreshing the browser fix it?

#9

I closed the browser tab and opened a new tab with http://127.0.0.1:8089/admin/settings -- and the problem was gone.

I just got the same JS error. My browser was on Up Next overnight while a new recording was added. I clicked to Unwatched and the new recording showed up, but also this error. Refreshing made it go away. Win 10, Firefox 71.0, Channels 2019.12.11.0456.

I cannot seem to pull the guide up on my AppleTV either.
I closed my browser window and re-opened and it still gives the error.
Did I hose the java on my dvr server host?

Edit. Works in Chrome but not Firefox.

#12

Are you running the latest Channels DVR prerelease version?

#13

No, not yet. I'll try it.

#14

How do I make the 'check for updates' button come back. Mine says 'up to date!' with no button.
edit came back a few minutes later. I think i'm good.
