The desktop app always believes it is offline

[AlbeyAmakiir]

• This is not a feature request (existing functionality does not work, not missing functionality).
  I will request features on forum or via support.
• I've searched and did not find a similar issue.

Describe the bug
Upon opening the desktop app, it tells me I am offline, even if I am not.

To Reproduce

1. Make sure internet is available
2. Open the app

Expected behavior
The login screen to display and allow me to log in to get my latest emails

Desktop (please complete the following information):

• OS: ArcoLinux (ArchLinux) 6.8.7-arch1-1

Additional context
I have had this issue for several months.
I have tried both with and without my VPN active. My phone is able to connect while on the same wifi as my desktop.
This is my latest attempt without VPN, though the logs are the same either way:
