Use anti-detect browsers (Multilogin, Indigo, LinkenSphere, Aezakmi) or deactivate WebRTC.

Linken Sphere will reload WebRTC if you change IP in Dynamic Socks 5

Dynamic socks5: for mobile SOCKS; every time you change IP it reloads page to substitute for WebRTC.

Deactivate WebRTC:

We either block media.peerconnection.enabled = false

or set it up to connect to a default IP address

media.peerconnection.ice.default_address_only = true

Google Chrome the WebRTC Block or WebRTC Leak Prevent plugin (there is one for Opera as well).
