I have tried to install the plugin on two different websites hosted at Greenhost (shared hosting), and in both cases the installation process never seems to finish. But when I move away from the install page to the plugin directory, it appears the plugin is installed, though not yet activated. After activating it manually, everything works fine.
UPDATE: When installing the plugin on websites hosted at Strato (shared hosting), the installation fails. Either you get an empty screen, or an error message (Secure Connection Failed. An error occurred during a connection to vvedewatertoren.nl) I have double checked and both websites are on the latest WP version (5.2.4), and running on PHP 7.2
UPDATE 2: When I manually upload the plugin via SFTP to Strato websites and activate it via the WP backend, everything works fine.
