H5P on shared hosting

I am using Hostinger for a Drupal H5P server. When I try to upload images or video over ~6Mb the site freezes and eventually loads install.php. 

I can go back to the content page but any content that has caused a freeze during production will not load and go to install.php again. The Drupal log has the 2006 mysql server has gone away error.

I asked Hostinger to let me know what the /etc/my.cnf settings were and if they complied with the requirements outlined here https://www.drupal.org/node/259580. They did not tell me the settings but told me:

“you should consider using a VPS with that, as it looks like it requires more resources than the shared hosting offers” 

In the time between my question and their reply I installed the Drupal Video module and successfully uploaded a 13Mb file, so I pointed that out. They replied:

“So, it’s not the 13mb upload the issue, but it seems like that the “script” or the “plugin” itself isn’t meant to be used on shared hosting environment”

Can anybody shed any light on this problem? Is H5P not meant to be used in shared hosting?

Thanks
