Additional context
It was working before but I don't remeber the component version (2 or 3 weeks ago) then some day it stopped working
Then I uninstalled it and installed again to start from scrach now I get this error.

Did you install something in the machine that host HA? There is an SSL error ('No cipher can be selected.'), looks like the machine is not able to establish the SSL connection with LG server.

It's the official docker image, so is not like I can install anything on it and I haven't done it anyway. Could you give me more clues of what could interfere with the SSL cipher selection?
I could do some troubleshoting but I have not idea where to start

[lordraiden]

I have HACS with this integrations but nothing else

[inorhan]

Hello.

I have the exact same problem, also "Es" account location, and "ssl.SSLError: ('No cipher can be selected.',)".
Was working before too.

I see more errors like that one lately: https://community.home-assistant.io/t/get-roomba-blid-pw-the-easy-way-using-windows/75107/20

ProxmoxVE integration it's complaining too (same "ssl.SSLError: ('No cipher can be selected.')

Maybe a problem with Python-Hassio?

[ollo69]

It could be. But did you update HASSIO recently?

[inorhan]

Yes, I have Home Assistant 2021.3.4, HACS updated too.

core-2021.3.4
Sistema operativo del Host | Home Assistant OS 5.12
Canal de actualización | stable
Versión del Supervisor | supervisor-2021.03.6
Versión de Docker | 19.03.13

I don't really know when started to fail...

[ollo69]

This is quite complex, I don't really know how to help. I thing that there are some configuration than provide supported cipher, but I don't know exactly where to find this. I'm not using HASSIO. If I have some time I will make some test with it, but I don't know when it will happen.
I suggest you to google your issue, and please post here if you find a solution.

@inorhan Try removing lines 115-125 of custom_components/smartthinq_sensors/wideq/core_v2.py #139

That worked perfectly, no more "ssl.SSLError: ('No cipher can be selected.',)". Thanks!!!

[ollo69]

Really good to know, working on final fix

[ollo69]

Can we close this issue? It should be fixed with last release.

[ollo69]

Close due to inactivity and because it should be fixed. Re-open if additional info available.
