Bug Description

Hi,

I have RustDesk server installed on my Synology in a docker. Version 1.1.9 worked fine, but since 1.2.1 update I get no connection when I try to connect outside of my local network.

DynDNS, ports, etc. has not been changed since 1.1.9 and I already resetted both, router and nas. Access to my DDNS is ok. I also completely deleted docker and reinstalled - unfortunately all without success.

Any ideas what could cause blocking access from outside? As said connection within my local network is no problem.

How to Reproduce

Installation on Synology docker using this guide: https://mariushosting.com/how-to-install-rustdesk-on-your-synology-nas/

Expected Behavior

Connection only works in local network or when not using own server

Operating system(s) on local side and remote side

Windows 11

RustDesk Version(s) on local side and remote side

1.2.1 > 1.2.1 or 1.1.9

Screenshots
