How to find the source of the “to many connections” error on a shared server? [closed]

I currently have a shared hosting plan and I’m having problems with the database connection limit.

I contacted support to at least help me find out the origin of these connections, scripts, IP, etc.

But they said they can’t tell me this (?) and that I’ll have to figure it out on my own.

The question is how can I do this on a shared plan, which doesn’t even have a way to list the processes? Is there any way to enable a log, I don’t know?

I use the Hostinger Cloud plan

I would like to somehow find out at least the script that is causing this, because the site is crashing with less than 10 hits and I pay ONE HUNDRED AND THIRTY REAIS for the plan. I also accept server recommendations, I thought it was absurd that support didn’t help me with this.
