1.If you have a VPN, you do not need to use a proxy server. Both proxy servers and VPNS mask your IP identity.
2. So there's no reason to use them together. In fact, if you're already using a VPN, connecting to a website or application via a proxy server just adds an unnecessary extra step and may even slow down without adding any additional security.
That being said, if you feel the need to take additional steps to protect your anonymity, you can use both.
If you need multiple different proxy IP, we recommend using RoxLabs proxy：www.roxlabs.io
