"Failed to establish a new connection" for several components

Installation Home Assistant OS

I’ve been fighting with this issue for a while now and figured it was time to ask the community.

Basically, I am experiencing intermittent failures with any cloud-based service. In particular, I have problems with Nest, tuya, and Darksky. When I try to set the temp on my Nest thermostat, for example, it will fail about 75% of the time. The errors I see are always the same: “Failed to establish a new connection: [Errno -3] Try again” (the errors are much longer, of course, but I believe this is the core of the issue).

I don’t have any other issues with my home network and have manually changed the DNS to 8.8.8.8. I don’t see any other issues with the networking side of things, just the cloud stuff. All of my local devices (Hue, mqtt, sonoff) run perfectly.

I appreciate any ideas or advice.

Set your logging level to debug and check the logs for excessive traffic.

When I did this I was surprised to see the volume of data that the Glances component generates. This was causing network issues for me occasionally.

Thanks for the help. Enabling debug helped me realize that my Tuya plugs were calling home every few seconds. I disabled that module and things are working much better now.
