Thunderbird has stopped connecting to the PTD server on every computer/account at my body shop

Someone may be able to help if you describe the symptoms.

Is there an error message? Can you send or receive? What does the status bar say when you try to connect? How are you trying to connect?

Are you sure that Thunderbird is in online mode?

It says that my login to promail.ptd.net with my username has failed. I get prompted to enter a password, it just repeats over and over again with no luck. I'm definitely online. no access to send or receive email. i've checked my incoming and outgoing server settings and tried basically every combination of options but no luck. "I get a little pop up that says server promail.ptd.net has disconnected. The server may have gone down or there may be a network issue."

PTD publishes these settings:

IMAP (incoming/host name): promail.ptd.net Port 143 (Default) Port 993 for mail applications that support using SSL/TLS

SMTP (outgoing/host name): promail.ptd.net Port 587 SMTP Authentication is required

Are you using them?

Does this problem occur with all four accounts? And you are not able to send or receive from/to all four?

When does the message about the server disconnecting appear? It may be accurate. Have you asked PTD if the server is down? I believe that webmail might still work even if an IMAP or POP server is down, so you cannot judge from webmail. Are you experiencing any network issues outside Thunderbird? Can you browse the Web?

Almost two years ago, an inquiry from you on this forum indicated that PTD was blocking your account. Have you contacted them and asked if they are doing it again?

Sure wish there was someone to call at mozilla. I have exhausted soooo many different options all to no avail.

This is the official support forum.

Those were the settings I had on. I spoke with PTD multiple times before reaching out here, they advised me no server issues on their end. I came in to work this morning and everything is just working so who knows what the issue was.

Thanks for your help

Perhaps a network issue, as the message said. You may want to inspect your local network for problems.
