@apollon77 awesome advice, I will definitely do that when I run into trouble and/or have something I want to start developing. For now, I have resolved the issue by buying a raspberry PI 4 and installing iobroker into it directly, so not in Docker. That seems to have solved quite a few network issues. I am now realising that mDNS also didn't work properly, I had to manually configure my chromecast in the plugin, now they all appear magically.

What I am seeing is that I apparently had the wrong port. I am now connecting to port 8009, not port 8008 as is the default I found elsewhere. I assume 8008 is probably without encryption and 8009 with encryption. How it can have worked in the first place I am completely puzzled by.

For now, thanks for the assist!

@apollon77 , I do have the devices and also have javascript web development experience. I would love to debug this in more detail. In fact, this might be an interesting side project to help maintain.

Could you advise on a method to test this in isolation? I'd really like to be able to run the code locally in a "unit test"-like setup and be able to debug the code...

@apollon77, SSL connections are somewhat more complicated, but it still sounds like it should just work. The reproduction steps for me are very simple, created an issue at the Google home project:

https://github.com/angelnu/ioBroker.chromecast/issues/80

sunsear created this issue in angelnu/ioBroker.chromecast

closed Unable to connect to Chromecast due to SSL/TLS-error #80

@apollon77, could be, I would expect a lot more errors in the community if that were the case. Strange!

BTW, 1 speaker is an LG branded Chromecast, but I also have a bunch of Google Mini's and a Nest Hub. None of them seem to be working well

Could it somehow be related to the fact that I am running iobroker in a Docker container?

@apollon77 , yes I did do a power cycle on my Google devices. There is some kind of connection error indeed, strange that it only started occurring last week, where it did work properly before.

Anyone else have this error?

Hi all,

Yesterday my Google Home adapter suddenly stopped connecting to my Google homes, which it did properly the day before. I get this error:

chromecast.0	2021-02-21 09:13:42.704	warn	(7899) Woonkamer - Client error: Error: Client network socket disconnected before secure TLS connection was established

This is to my Google Nest Hub, but the same thing happens to my LG WK-7 Chromecast audio. I cannot seem to find anything that I have configured wrong, can anybody provide a hint? Maybe @vegetto ?

Thanks in advance,

Martin
