Are you accessing code-server over a secure context?

• I am using a secure context.

Notes

Running npm install vsda in /usr/lib/code-server/lib/vscode is not a valid workaround and generates other issues:

This (or something similar) is happening to me with SSH in VS Code 1.96.2, But only on some hosts. I tried using a friends host which was c6g.4xLarge, and I had no issues. On my c7g.4xLarge I have this issue. In vs code Server output I get
[error] ptyHost terminated unexpectedly with code null, I've tried the usual, deleting .vscode-server, reinstalling vscode locally, Extension Bisect. I even replaced the host with a fresh one and it's still happening. When I ssh via local terminal (mac) I have no issues staying connected. Only in the vs code terminal do I have issues.

Edit: I ended up just downgrading to c6g and it fixed.. I guess there is some kind of connection throughput limit to c7g.
