[ReenigneArcher]

Clicking that notification pairs the client or opens some dialog to pair the client.

It is supposed to open the web ui. Does the open sunshine option work from the tray icon?

Please restart Sunshine, and try to do a pair again. Then share the full logs.

[abrandst]

Rebooted, and restarted sunshine. The Web UI opens normally from the task bar. The logs below are all from before the pairing - the pairing request does not generate any log entry, nor does it show up in the web ui itself.

No idea, they're almost the same exact code.

Sunshine/src/entry_handler.cpp

Lines 29 to 37 in 64544e7

	void launch_ui() {
	std::string url = "https://localhost:" + std::to_string(net::map_port(confighttp::PORT_HTTPS));
	platf::open_url(url);
	}
	void launch_ui_with_path(std::string path) {
	std::string url = "https://localhost:" + std::to_string(net::map_port(confighttp::PORT_HTTPS)) + path;
	platf::open_url(url);
	}

It's called from:

Sunshine/src/system_tray.cpp

Lines 308 to 310 in 64544e7

	tray.notification_cb = []() {
	launch_ui_with_path("/pin");
	};
