Xfinity TVE cannot login: Invalid URl for request

I installed Channels DVR on my Linux box. Created an xfinity user without billing access. Turned off auto authentication. Ensured 2FA is not on the user. When I try to add a TV everywhere source, I put the xfinity username in and password and get the following error:

could not dial "127.0.0.1:41537": parse 127.0.0.1:41537: invalid URI for request

Any ideas?

Did you verify that you can use the login credentials through the Xfinity Stream app or through a browser? Never seen that type of issue myself.

The devs will probably ask you for more log data than just that one line.
IP addr 127.x.x.x is localhost, so seems kinda wierd for Channels TVE.
My Xfinity TVE works on my linux box.
Just another thought and I haven't experienced it, but others have mentioned that you should be using your Xfinity(Comcast) username and not your email address for the username. I.E. username, NOT [email protected]

I did verify the credentials worked through the browser, and I was using just the username and not the entire email. I tried rebooting and that didn't help.

I finally resolved it by doing the software updates in Ubuntu, which had lots of updates (it's a box I don't update regularly), but one of the updates was an update to the chrome browser. Once the updated system rebooted, I launched the new chrome and the comcast authentication magically worked. I suspect it was something to do with the old version of chrome originally on this box.

This is what the log showed before it started working:
2019/09/06 22:56:42 [NAT] Successfully mapped port 8089 using natpmp
2019/09/06 23:03:41 [TVE] Auth starting for Comcast_SSO as channelsdvr
2019/09/06 23:03:41 [TVE] action=auth mvpd=Comcast_SSO requestor=nbcentertainment
2019/09/06 23:03:41 [TVE] Auth failed for Comcast_SSO: could not dial "127.0.0.1:44581": parse 127.0.0.1:44581: invalid URI for request

So, now it's working fine just thought I'd post this update in case it helps someone else

This is due to too old chrome. What version is installed?
