Lost email thread: Ah, Snap! Something went wrong while fetching the thread. Please hold on for 5 seconds

Then I get:  "Content is not available. Please try again after some time." 

I have logged out, refreshed countless times. How does an email program just lose an email thread? 


****edit this is happening on all my open tickets now******
