The app page looks like its loading but when it is done is show an empty page

Nextcloud version:
Operating system and version: Redhat7
Apache or nginx version: apache 2.4.6
PHP version (eg, 5.6): php 7.0.15 with opcache and php-fpm
Is this the first time you’ve seen this error and can you replicate it?:

The issue you are facing:

I have installed nextcloud 11 in a cluster, this cluster is in development.
1 haproxy
2 app servers
in the app servers a haproxy for load balancing to mariadb
3 DB servers
1 NFS server

The installation went without a hitch. I can open the webpage from outside an do everything.
But as soons as i want to open the app page it’s starts loading and then it only shows a blank app page.

I followed the general troubleshooting in the admin guide. There are no SELinux problems. (we enforce SElinux) only the occasional database has gone away. I have increased the max allowed packet to 100M and wait timeout to 28800. but it still pops up sometimes.

I would like to receive any assistance to resolving my apps page issue.
