Secure Connection Failed PR_CONNECT_RESET_ERROR over Certain Wi-Fi Network Only

Every time I am on a certain Wi-Fi Network (usually public networks), I encounter the "Secure Connection Failed" Error message.

Secure Connection Failed

An error occurred during a connection to [website.domain] PR_CONNECT_RESET_ERROR

Error code: PR_CONNECT_RESET_ERROR

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

In the Corner of the URL bar, it says "not secure"

you are not securely connected to this site your connection to this site is not private. Information you submit could be viewed by others (like passwords, messages, credit cards, etc.).

I've tried almost every troubleshooting decision I could find:

-clearing cache and restarting browser

-Updating my Browser

-Messing with the Proxy Settings

-disable DNS over HTTPS

-about:congig security.tls.enable_0rtt_data & network.http.http3.enable to false

-Creating new profile

-deleting cert9.db file

-opening in Troubleshoot mode

None of these solutions that I could find online works at all. Websites work perfectly fine in other browsers, just not Firefox, which is particularly aggravating because I would much rather use FireFox. and the self same sites work on other networks, just not the one's I am reliant on atm.

Please help.

Mac OS Ventura

FireFox 130.0 (64-bit)
