Multi php version server: chosen php 7.2 HC reports 5,3

I have my wordpress hosted on the server where one can choose among many versions of php. I set to 7.2 as info.php indicates: https://duziomiodu.pl/info.php
HC however reports the issue with php version and loopback:

The REST API encountered an unexpected result Performance
The REST API is one way WordPress, and other applications, communicate with the server. One example is the block editor screen, which relies on this to display, and save, your posts and pages.

The REST API call gave the following unexpected result: (500) Your server is running PHP version 5.3.28-0+tld2 but WordPress 5.2 requires at least 5.6.20..

Your site could not complete a loopback request Performance
Loopback requests are used to run scheduled events, and are also used by the built-in editors for themes and plugins to verify code stability.

The loopback request returned an unexpected http status code, 500, it was not possible to determine if this will prevent features from working as expected

It results wiht the loopback biases like vesion check is blocked as well as it is imposible to edit php files.

I have switched off all the plugins and run pure 2017 theme.
I have contacted the hosting support and have a respod that HC calls domain locally with no use of proxy, which directs to the server wiht proper php version. Which in their opinion is a WP bug.

I experience the same isuue with the other site hosted there: https://czarter-jachtow-mazury.pl

Can you help?
Thanks
