I can’t seem to get a better job unless I know someone.

I've been applying for a new job since the pandemic from regular on site jobs to work from home jobs and all I've gotten were rejections. The only reason why I got my current job is because my dad knew someone who is a friend. My previous job I had was also a dads friend of mine. If I just blindly apply to jobs on job search sites I hear nothing. Anyone else struggle with this?
