View Posts Button Shows 404 Error

I just posted my first blog post, and I had someone let me know when they click the “view posts” button on my homepage, it takes them to a 404 error page not found.
I am able to access the blog post from the drop down menu on the homepage but clicking the “Blog” page. I have been trying everything to fix this issue and nothing is working. I installed the site health and troubleshooting plugin, and that says everything looks good.
Please help!
