Heartbeat always gets touched even with no active connections when connected from iPad Safari
nullpo-head opened this issue · comments
The same problem as #1795 is still happening with 3.5.0 only in Safari on iPad.
Even after closing all tabs or even browser, it seems Code-Server recognizes 1 active connection. Because of that, Heartbeat keeps getting touched.

I’ve confirmed that this phenomenon doesn’t happen in Chrome on Windows/macOS, nor Safari on macOS. It seems to happen only in Safari on iPad OS.
FYI, this is the log when I connect to a Code-Server instance by desktop browsers.

BTW, I’ve noticed this problem while I’m testing Out-of-the-Box-CodeServer, which is an easy setup tool of Code-Server. So, you can reproduce the environment by the tool if you need.
- Web Browser: Safari
- Local OS: iPad OS 13.6
- Remote OS: Ubuntu 20.04
- Remote Architecture: amd64
code-server --version: 3.5.0 de41646
Bizarre! What does sudo ss -tpn output?
In #2112 @OliverwengFiltered was able to reproduce with chrome on macOS.
