Cannot upload to dropbox

Hi guys,

Been getting errors with backing up to Dropbox. I’ve checked dropouts and there seems to be no current issues. I was having problems with port 443 errors but I seem to have solved that by setting higher limits in htacccess for timeouts and fileesize via php_value. Check with my host and they say no changes have been made.

This is the first time I’ve ever had issues with this.
