I tried creating a custom php.ini file however it hasn't worked. I sent an email back to support but I haven't got a response back yet. Below is the email I sent to Jay and also his recommendation.
Any help you could give would be greatly appreciated as the site has been down a few days.
Thank you for your help. I created a custom php.ini file however I'm still getting
the 504 error. I'm hoping I created the file correctly. I placed the file here:

Once you've done that you can then set the "max_execution_time" to higher
value such as 100-180 seconds and that might resolve this. This appears
to be a problem with the Concrete5 system. I see that you've created the
following forum post and that is good as well:
Please attempt to change the max execution time and that should hopefully
help. If that still does not seem to work let us know and we will assist
