vscode-php-debug: Breakpoints not working when performing remote debugging

Everithing seems to be working ok. Adapter connects and detects scripts running but it NEVER stops on set breakpoints. Details:

• When setting a breakpoint it always states “unverified”.
• Next, after a script is executed the log indicates that it’s working (started, exited) but it seems that any breakpoint is actually set/reached.
• Mapped routes seems to be OK too.
• Nothing is logged on XDEBUG logs
• XDdebug / Webserver running under a Vagrant VM
• Server is running on port 8081 (http://127.0.0.1:8081)

Has somebody an idea of what to try next? I’ve been fighting this for two days, I’m a little frustrated 😦 Thank you in advance!
