FreePBX dashboard very slow to load

FreePBX is a well known and widely used User Interface for managing and controlling asterisk server. I am using FreePBX for the last 3 years. It’s simple, easy to use and widely supported software. FreePBX is the leader in the IP PBX category.

Problem :

Well, sometimes it’s hard to find out a working solution when a problem comes once in a while. I am having this problem with its dashboard since I installed FreePBX 14. It just stuck on 75% when reload and took at least 60 sec to 180 sec to load.

When I check-in console, /admin/ajax.php?command=getcontent&module=dashboard

This URL is taking 60 sec to respond.

I also checked in apache logs but nothing wrong is there. Also, I looked for the server load but it is normal and did not seem problematic. After all the checks and findings, I decided to roll back my changes one by one in reverse.
