DNS Leak and open port detection if using shield

Hello!

Hope you all are doing well. I faced DNS Leak and open port detection issue if I use shield. If I disable shield then it works fine. I am using tuxler vpn extension in my brave browser for long time without any issue. When I use tuxler vpn extension in Mozilla it works fine but from latest brave browser update I faced this issue. Mozilla firefox and chrome works fine but I loved use brave browser. I already talked with tuxler support they told no problem from their side. When I checked with brave shield enable/disable then I found this issue. I never face this issue before. please fix this issue. I submit 4 screen-shots 2 is enable shield and another 2 is disable shield.
