If you still want to use Uptime Monitor, set it’s interval slower. You can try 10 minutes, and if you still suspended next day, try 30 minutes or 1 hour.
Thanks for reading, bye for now
Almost every monitor does it not just Uptime robot, it is sending requests to your website every (the number you’ve chosen) minutes. if it is doing it on a page which consumes lots of server power in every visit then it is expected.
I use uptime monitors for my repl.it bot just to keep it running.
