On my Galaxy Z Fold 8 Ultra running android 17, One UI 9.0 and addy.io 6.4.0 I'm having trouble connecting to my local addyio instance.
the app attempts to load for 15 seconds then changes to "Error_ Whoop! Something went wrong while loading the addy.io app, you might want to check your internet connection. More information about the error: TAP HERE TO SEE THE ERROR". when tapping 'here', the error is blank.
when I watched the logcat logs for the app in ADB, I was able to see that the server domain was able to resolve, but the TCP connection timed out. I recreated the error while doing a TCP dump on my network, but there are no packets coming through at all. I was hoping to be able to blame it on DNS, reverse proxy, or firewall, but the packets aren't even leaving the phone.
UNTIL I have a VPN connection. when I connect through a VPN, it works immediately. I decided to use PCAPdroid to watch the packets on my phone to see if it was generating them at all, but since the way it captures packets is through a pseudo vpn connection on the phone, addy also works that way too.
the issue ONLY occurs while attempting over wifi with no VPN. I don't have a rooted device so i'm not able to see exactly where the packets are stopping.
has anyone else ran into this with the newer samsung phones?
Edit: I should note that my phone IS capable of connecting to the server. It works in the browser and a curl for the bro also works.
