2 years ago That's odd. The ready event only gets called once the library is able to perform a suceseful GET request to the API as you can see here. This problem is more likely related to the environment where you are trying to run the library in. Can you provide more details about this?
I'm running a script to launch League Client and some python script to fetch some data from it with the help of lcu-driver(Thank you for your great work and sharing).
This is being done in a cheap remote server, to be specifically, an Azure B1S instance(1vCPU, 1GB RAM).
Probably because of its poor performance(it takes almost 5 mins to finish loading from graphical perspective), even when connecting to it when ready() is fired, it's giving error like this

aiohttp.client_exceptions.ClientConnectorError: Cannot connect to host 127.0.0.1:50763 ssl:False [The remote computer refused the network connection]
I tried to solve this by just waiting for 5mins after the ready() is fired. But it's causing another problem, the connection seems to be timed out so an ConnectionResetError: [WinError 10054] An existing connection was forcibly closed by the remote host is raised by CHANCE. Sometimes it works.
I could possibly fix this by using two connectors one just to detect the launch of League Client(by ready()) and sleep 5mins, after that just close and use another connector to my job. Don't know if it will workout.
But I guess ready() is not working as expected(it's not ready yet!). Or is it? So a fix to ready() would help very much. Or maybe I'm miss using the driver, is there anything I should try?
