For testing purposes, let's try the Opera VPN browser:
Turn on Opera VPN on your device and click on the “Get Started” button.
When we see a question on the display about permission to connect, we answer in the affirmative.
After clicking the "Connect" button, all outgoing traffic will be processed by Opera servers located in Germany, Canada, the Netherlands, Singapore, and the United States. The application automatically connects to the one that is closest to the user's device. You can choose any other, but the further the server is, the more the data transfer speed drops.
A key icon should appear at the top of the phone, which means the VPN is active. Try to go to the site that previously gave the 403 error. If you were able to log in, then the virtual machine is working fine.
