[BUG] No file gunicorn.ctl

[BylgakovAN]

What happened?

Hei!
The ui.log constantly reports "Control server error: [Errno 13] Permission denied."

[UI] [6213] [❌] - Control server error: [Errno 13] Permission denied

I added information about this error to the /usr/share/bunkerweb/deps/python/gunicorn/ctl/server.py file (sorry if it's incorrect).

    def _run_loop(self):
        """Run the asyncio event loop in background thread."""
        try:
            asyncio.run(self._serve())
        except PermissionError:
            if self.arbiter.log:
                self.arbiter.log.error(f"""Permission denied: {self.socket_path}""")
        except Exception·as·e:
            if self.arbiter.log:
                self.arbiter.log.error("Control·server·error:·%s", e)

It turned out that the file doesn't exist. gunicorn.ctl

Is this how it should be? The file really doesn't exist.

This way it's probably easier to see.

Hi @BylgakovAN,

Thank you for opening this issue. We’re aware of the problem and have confirmed that it does not impact the web interface runtime.

We’re preparing a release candidate today that includes a fix. We’ll follow up once it’s available for testing.

Hi @BylgakovAN, this has been fixed in v1.6.9 🎉

Control socket configuration has been added for both the Web UI and the API gunicorn instances. Thank you for the detailed analysis!
