Unexplainable internet connectivity

This is my first post here, so I’ll try to follow necessary conventions -
I’ve been using Parrot OS for months, so this isn’t a new installation thing - it’s actually a very confusing thing for me.
I run Parrot OS virtually with a windows host… it’s my primary OS
yesterday, I open FF to get on the internet and couldn’t connect. I had been on the night before with no problems and hadn’t changed anything since - I literally went from online to sleep to online again, but this time I couldn’t connect. The first things I did was check to see if anonsurf or my vpn was running and neither were.
At the time I was using the wired connection to my host. So I connected my host to my neighbors wifi but still nothing, I tried with a wireless ext. NIC - still nothing.
I tried Nmapping a few hosts by domain name and was getting failure to resolve issues. Tried the same scans using IPs and no problems so I starting thinking it was a DNS issue.
I opened Tor and had no problems, so now I’m thinking port issue
nmapped myself and saw port 80 closed
Did some research and ran a few iptables commands, neither of which worked.
Then realized that I didn’t have to use Tor or my host browser because I could probably connect using anonsurf (different port) which worked.
Searched through the forums here, as I am now and came across ‘unix-privesc-check’ which I ran in standard mode.
Got a warning that I will post about in a separate thread.
Did some more researching and decided to try connecting without anonsurf… I’ve connected fine, no issues
BUT nmap still shows that my port 80 and 443 are closed

I have no idea what happened here, and am hoping someone has the time and will to break it down for me
Everything seems to be working fine now, but truth is that I’ve no idea how it got like that nor how it was remedied

My system specs are as follows:
