Super confusing ZAP error: [java.net.SocketException]: Connection reset

[REWWa]

Thank you so much for reading this!!!! I'm struggling here
I'm getting an error page when proxying my browser with ZAP(127.0.0.1:8080)

specific for one website that I am trying to visit
error occurs like when I use AJAX spider(because AJAX spider is basically using my browser to crawl)
it was fine when I ran standard spider(yes I ran a standard spider)
full error here:

"
and I've checked the server response
there isn't even a response just blank
and this error page shown in the browser

for other websites ZAP proxying works fine

I'm running it on a Kali VM using NAT mode
I've tried restarting my VM and ZAP, and checking configurations

and I wonder if the website blocks me or something?

whereas it's just a normal website not something super secure and the error doesn't seem to be related
last but not least

like about one day or two days ago

I remember visiting that website with ZAP proxying on and it was somehow successful

what I mean is that sometimes that error is thrown

(and at that point I remember the error was different, goes like "connect pool" "illegalstate" or something can't remember it sorry)

but sometimes

I can successfully visit that website and get responses, with a browser(using Firefox) warning indicating insecure connection, which is also confusing because it uses HTTPS.

actually here's the website: https://xmyz.xmedu.cn/

(don't worry I'm not doing any illegal hacking this is actually a school website and I've queried relevant teachers and they say it's fine to hack the school website if I can lol)

I hope my statement was clear

if any further details would help please let me know

sincerely appreciate if anyone could help

thank you!!

btw I am using ZAP 2.12.0

TYSM!!!!!
