Mailspring: Bug: Connectivity issue after suspend or change of network

[pendula95]

Are there any related issues?

Yes this issue partly covers it, alongside the issue described here I have issue same as here #468

What operating system are you using?

Fedora release 29 (Twenty Nine) x86_6
Kernel: 4.20.15-200.fc29.x86_64

What version of Mailspring are you using?

mailspring-1.6.0-0.1.x86_64

Bug?
When mailspring is in tray/background when network is changed or when my laptop wakes from sleep I get error Several of your accounts are having issues with options Check Again and Manage. If I click Check Again everything works.

Is this an email sync or connection issue?

mailsync-c67d0374.log

mailsync-7f167e86.log

Is the issue related to a specific email provider (Gmail, Exchange, etc.)?

No, all accounts fail.

Is the issue reproducible with a particular attachment, message, signature, etc?

Happens when network is changed or laptop is resumed from sleep or network dies and then reconnects.

I have the same issue. Are there any updates?

This is really the main problem for me. We must trust our software, but I cannot be sure that the mail will be delivered on time.
I have to constantly check whether this error has appeared because I can miss an important letter and not react as I should.
@bengotow Does it have some architecture limitations to work it properly?
Can we have some system notifications to don't miss this major warning?
