[3.1.4] Update not working

[reginfo]

Hi,

Tried to update from 3.1.3.14 to 3.1.4 but stuck in first screen.
After providing admin credentials and hitting start button, page stuck with gear icon spinning.

Errors from console :
jquery.min.js:2
POST https://xxxxxxxx/install/upgrade_ajax.php 500 (Internal Server Error)
