thunderbird failed to connect to mail.comcast.net first time only, on TB startup only.

Just about every time I start TBird, I get the failed msg.
clicking Get Messages then gets both gmail and comcast.
subsequent auto access (every 5 min or so) work fine.
Ubuntu.
I believe this started when I shifted from 18.04.1 to 18.10 Ubuntu.
Only happens on that first access to comcast.
TB 60.2.1 64bit
POP account

Try pinging that server from a console window to see if it loses any packets.

https://www.febooti.com/products/automa ... email.html explains how to ping a smtp server but you can do the same thing for a POP server.

Pinging mail.comcast.net gives this error "ping: mail.comcast.net: Name or service not known"

I'm pretty sure I tried clicking Get Messages, and it didn't work. I'll have to see if I have one version of Thunderbird that still has that server configured and try again. Nope didn't work.

Changing the Server Name to "imap.ge.xfinity.com", accepting the certificate exception, click Get Messages, enter your password works.

See: viewtopic.php?f=28&t=3043891 and https://ubuntuforums.org/showthread.php?t=2406399 for other options.

Thanks! That gave me some vital info, like it started on Nov 19, which probably matches my experience. However, with them, they don't seem to be able to get it to work at all, whereas for me it only fails on the first access

I will mark this solved and ignore it.
Thanks!!!

edit - pinging it produces
Code: Select all
kris@kris-ThinkPad-T530:~$ ping mail.comcast.net
ping: mail.comcast.net: Temporary failure in name resolution
kris@kris-ThinkPad-T530:~$ ping mail.comcast.net
ping: mail.comcast.net: Temporary failure in name resolution
kris@kris-ThinkPad-T530:~$



so I was wrong - it is happening every time.
But I want to be pop, not imap...

HUGE thanks to all. I will wait for a bit and see if this gets fixed by comcast (Godot). I would hate like heck to change to imap, so I may just revert to using their web site. I only use it for my comcast bills.

Thanks!!!

Unless it's something specific to the Linux version of Thunderbird, there doesn't seem to be any problem accessing Comcast's POP servers running Thunderbird 60.3.1 under Win10.
