1 month ago @xMidNightFTW Hello! What is your server's Ubuntu version? Is your virtual machine in the cloud or on a device in your home network?
This could be an issue with IPTables rules on your server. Please run the commands in issue #38 to check the IPTables rules, and try the 3 troubleshooting steps in my comment in that issue.

As for trying a different client please suggest something i just scan the qr code not sure if there's another client similar to wireshark
My home router is TP-LINK VR300 I disabled any kind of firewall on there btw.

1 month ago I found out the issue omg I am so stupid I had the virtual machine in NAT thank you You can close this
No internet when connected from client i did everything correctly but everytime i connect from a client to the server theres not internet and i tried multiple devices from many different networks. I'm not sure if i am doing something wrong here
I have the script installed on a virtual machine running Ubuntu
There's a closed issue with the same problem but there seems like it wasn't solved.
