No matter what I try, I am getting SSL errors when i connected to Wi-Fi's except home Wi-Fi

My Laptop has a problem on network side. I am using the Wi-Fi's of many different places very fine with my phone but not with my PC. It used to not open couple of websites due to SSL error but it was opening most of them. Right now it does not open none of them. No matter what i tried it did not work. I am master's student on computer engineering so you could assume the things that i try. (Clearing cache, network adapter settings, check the proxy, update the driver and all. But still it does not work. I got help from AI's as well but it still does not work. Please need your advice here.)

I only have a couple of general thoughts. Since the Secure Socket Layer is in the Application layer of the OSI model I would try resetting the Winsock Catalog. I would also try a different browser to see if there is an issue with your current browser (installed Certificate authorities, SSL/TLS version).

You can try using the browser Development tools to look at the security certificate and also see the TLS version when a connection is made or perhaps why it failed. For the Edge browser, open settings ( . . . )  > more tools > Developer tools.

The first time you use it you'll be at the Home screen. Click the "+" on the far right of the tool icons for more tools and scroll down and find Security (padlock icon). It gets added to the top pane tools bar.

Try browsing to a website and maybe it will provide a clue.
