[Davmail-users] Problem "All network interfaces down or host unreachable"

[D <ka...@ai...>]

I use davmail with an office365 email account and it works fine.
Now I'm trying to configure another account, on a separate davmail instance
(both instances are server instances).

The relevant config is, as per instructions:

davmail.url=https://outlook.office365.com/EWS/Exchange.asmx
davmail.mode=O365Modern

With the new account, when I attempt the first login I see an auth URL in
the logs, which I open manually, and give the required permissions to the
application. I seem to remember that, with the working account, on
subsequent connections I got an authenticator request which I approved, and
from then on everything worked fine.

With the account I'm trying to setup, when I connect again to davmail,
I get the following errors in the logs:

davmail-acc    | 2022-07-20 21:03:42,700 WARN  [ImapConnection-58118] davmail.exchange.ExchangeSession  - All network interfaces down or host unreachable !

Don't know where to look as, like I said, I have another identical setup
which works.

Thanks for any help
