Like said in the long title, I can't access my site hosted on AWS with AWS Route 53 Hosted Zone. When I initially configured my DNS, there may have been something wrong with the A records which resulted in a server not found. I updated my DNS configuration and my laptop still cannot access it.
However, the updated DNS configuration is correct such that when I use a different laptop or use my friends' phones (some tested at my home using my WiFi and others tested at their own home with their own WiFi; all of them worked for my friends regardless of the device), it works fine. When I do an nslookup from my laptop, it says ** server can't find hearye.us: SERVFAIL. But when my laptop (a MacBook Air) is connected to my phone's personal hotspot, it works fine.
I tried changing wifi networks (two completely different wifi networks at two different locations) to no avail. I also tried flushing my DNS cache using this: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder.
Also note, I tried testing this on my iPhone 6s during the incorrect DNS configuration. So my iPhone 6s has the exact same problem. If it's on WiFi, it fails, regardless of which WiFi. If I use my cell data/network, it works fine. Hence, when my laptop was connected to my phone's personal hotspot, it connected since my phone was using cell data.
I also ran this but didn't receive any A records:

Now, I actually don't understand what dig does; I just found it online. Explanation is not needed since I'll try to learn it myself unless it relates to the problem.
I also went to the public IP address you see in the A record, and the website (a default nginx page that I didn't bother unlinking) loads just fine.
Finally, restarting, shutting down, etc. (not really willing to factory reset) my laptop or phone does not work.
Any guesses as to what could be the problem and/or how to resolve?
