Sometimes when you using VPN connection with Ubuntu and run angular project command ng serve get next error.
I share 2 solutions:
Solution 1
1. run next command on your angular project.
ng serve --ssl true --ssl-cert "./ssl/localhost.crt" --ssl-key "./ssl/localhost.key"
Use incognito google chrome to go to http://localhost:4200
This solution work for me using Ubuntu 20.04
Solution 2
2. Go to developer tools Chrome 3 dots > More tools > Developer tools
2.1 Right click on the refresh button > select > Empty Cache and Hard Reload
2.2 Then type http://localhost:4200
