Having the same issues here with "Loading" message on AJAX, and on HTML a message page without the icons. Running MOBILE on the desktop is functional under Firefox. Phones still syncing, and I started up the old Zimbra Desktop that I have not used in years, and it appears to be syncing ok. Everything was working fine up to 17:15 EST, but at 21:00 this problem came up. Nothing has been changed on the box in months, been running fine. I actually have a new server here, just waiting to be moved this coming week. Firefox, Chrome, and IE exhibit the same issues. Using the generic Samsung browser on my phone in MOBILE mode appears to be fine. HTML and AJAX have the same issue as the desktop browsers.
I'm running on this server
Ubuntu 14.04.05LTS
Zimbra 8.6.0_GA_1169
ZExtras 2.6.5
SSL's are good, and provided by AlphaSSL
