Did I get that unlucky and get assigned a bad IP?

Its mobile data btw.

And I don’t wanna point fingers and blame Proton, but like… c’mon,

First of all, its a real IP address,

Second, even if it were a VPN, so what, your company literally runs a VPN lol, kinda ironic.

And its also a paid account, and I rarely (almost never) send outgoing emails.

But again, this is just a small annoyance, I generated a new password in Keepass and its seems fixed.
