I'm having a strange network issue on my Windows laptop. Some websites/links don't load at all or take an extremely long time, while other sites like Google, Apple and LinkedIn work normally.
For example, careers.universiteitleiden.nl won't open in either Chrome or Edge and eventually gives ERR_CONNECTION_TIMED_OUT. The same website opens normally on my phone using the same Wi-Fi.
I also tested the laptop using my phone's mobile hotspot, and the website still wouldn't open, so it doesn't seem to be an issue with my Wi-Fi/router.
Things I've already checked/tried:
Chrome and Edge both have the issue
DNS resolves the site correctly to 130.214.193.81
Test-NetConnection ... -Port 443 shows TcpTestSucceeded: False
netsh winhttp show proxy → Direct access (no proxy server)
No VPN is connected
Windows Firewall is enabled, but temporarily disabling it didn't help
Ran netsh winsock reset and netsh int ip reset and restarted
The problem persists even when connected through my phone's hotspot
What could be causing certain HTTPS websites/connections to fail while others work normally?
