IPv4 fallback
UnderSampled opened this issue · 4 comments
I am on a network that has ulogger attempting to connect through IPv6, while that connection cannot be made for one reason or another. I am, however, able to view the webpage of the server I am connecting to, as my browser falls back to IPv4. Is there a way to do something similar in the mobile client?
Documentation for HttpURLConnection says that "this class includes transparent support for IPv6. For hosts with both IPv4 and IPv6 addresses, it will attempt to connect to each of a host's addresses until a connection is established."
Hard to tell why it fails in your case. It may be difficult for me to reproduce it.
When I find some time I will try to simulate similar scenario and check for possible problems.
What is the error message?
What is your Android version?
I tried starting a new track, since the error didn't change even with different networks, and that cleared it so I cannot show you. It basically said "cannot connect to (my domain URL) at (server ipv6). Now it says '"upload started" and does nothing (no error l, but stays behind.)
I am on Android 11.
