Maybe your WordPress is causing the server your website is in to create CPU spikes that cause your account to be suspended. Try after 24 hours to install a caching plugin like Autoptimize and pair it with WP Super Cache, so the CPU spikes will be gone. Then point the domain with ns1.byet.org and ns2.byet.org nameservers from Freenom’s “My Domains” Panel, because it won’t work with HTTPS connection!
