The weird thing is, in last 15 minutes someone from USA - AWS instance, 35.167.235.231 - tried to connect to my account. This app is said to sync locally, right? But I see no attempts from my IP in Outlook.com panel, but about ten from AWS. All of these started when I installed Nylas and tried to configure it; remaining logins logged by Microsoft are 100% by me (web client, iPhone Mail.app). WTF?

2nd edit: According to https://github.com/nylas/nylas-mail/issues/3405#issuecomment... someone else is unable to connect with GMail because of Nylas servers throwing HTTP 502. Does it sync locally or through Nylas' AWS instances? Is this why I can't configure my account with IMAP?
Not sure on the exact details of your account but if you send a quick note to support@nylas.come one of our engineers can look into it.
edit: Looks like it tries to fetch some PNG file, but all it gets is HTTP 502, I guess. (https://a.pomf.cat/xiblzy.png)
Edit: well, I'm low on coffee today. Just press Alt key to show the menu! Not a nylas problem :)
