Same issue here, Directv Stream will not authenticate with TV Everywhere. I first noticed it last night and it is still failing this morning.
Same issue for me. CHDVR will not tune TVE channels from DTV, but no problems from YTTV. I use the DTV and DTV stream sources.
I checked my test server and got the no password error with Directv.
Synology server
As a test, I was successful logging in to DirecTV's TVE in my browser on my laptop. I went to https://www.tntdrama.com and watched something without issue, so it definitely allows TVE logins that way.
It's been so long since I've done it that I'm not sure what, if anything, is new. But it does go to ttps://identity.directv.com/weblogin/authenticate which asks for my username. Then once I enter my username I'm brought to a second pane (seemingly via JavaScript) that lets me enter my password.
Perhaps that part is new and ChannelsDVR needs to be updated to follow along there? 
Edit: I've submitted my logs as 180e9cab-91e7-4d59-b102-4839b72a804f in case that helps (and also emailed support, as instructed when submitting my logs
).
I’ve submitted a diagnostic from my test server, in case it helps.

That did it! Thank you
This did it for me also. Much, much appreciated!
