With CloudWays, you should have shell access to your server. You can create a cronjob something like this:
15 * * * * /usr/bin/curl https://example.com/synBLAHate.php --connect-to ::22.214.171.124 >/dev/null 2>&1
This runs the job at 15 minutes after every hour. And replace the 126.96.36.199 with the actual IP address of your server so it connects directly.
I suggest you first test it manually from the command line:
/usr/bin/curl https://example.com/synBLAHate.php --connect-to ::188.8.131.52
Sometimes I end the cronjob line with
>/tmp/cron.txt 2>&1 instead so I can periodically look at that .txt file to see if the job is working properly.
