Unable to display this Web Part. To troubleshoot the problem. - Data View Web Part in o365

I have created a Data View Web Part with 5 levels of grouping and custom XSL. When I tried to refresh the page sometimes it give me error and sometimes it works as expected.

I have checked this msdn blog and found that by using below command this issue can be solved.

$farm = Get-SPFarm

$farm.XsltTransformTimeOut = 5

$farm.Update()

I am doing this in o365.

Please help its urgent.
