My phone email client suddenly cannot receive emails (IMAP). No changes were made ...

Hello Friends:

I made no changes to my Android phone settings or my Android email client settings (AquaMail).
As of 8:55AM this morning (New York City / Eastern time), my email client cannot download messages.
I can send emails as normal (via the SMTP protocol), but I cannot receive emails (via IMAP protocol).

The mail client error that I get is:
  • Error checking mail: Network Error: Unexpected end of network stream.
My network is fine. IMAP is still enabled on my account (I checked). This error happens whether I'm connected via WIFI or via Mobile/LTE

What happened? Can someone look into this on the server end?

Thank you!
