300 TIMEOUT LIMIT ERROR FOR DEMO INSTALATION

Good day,

When I try to install any of the demos I receive an error message that there is a timeout error and I need to contact my hosting provider because it needs to be atleast 300 seconds.

I upgraded my hosting to the following values and I am still receiving the error

max_execution_time – 6000
max_input_time – 6000
max_input_vars – 10,000
memory_limit – 768M

Please help, a screenshot of the error is attached.
