I've got a pair of Nests at my house behind a PA-200. Almost all the connections end up with a client reset, but everything works for my Nest reporting and login. My phone can manage them just fine, and I can see all my historical data. I think that Nest is just really aggressive with TCP handling.
Here's a screenshot of my logs. You'll notice that everything ends with rst, but the byte sizes are significant:
Hope this helps,
Thanks for the prompt reply.
I have very similar logs. Problem is it is always offline and can not be controlled. As soon as I remove the PA-200 and switch to an old school wireless router it works fine.
Any thoughts on what settings to tweak, what to look for to try and figure it out? etc.
The problem the Nest is having (or at least mine was having), is that it is trying to use the dropcam app on a non-default port (tcp-9543). if you're using policies that use application-default to allow your nest traffic out, it won't work.
Add a rule that allows dropcam (& web-browsing) outbound using tcp-9543 (along with your regular app-default outbound rules) and you should be golden.
Its 2020 and i also had the same issues of all 8 of my nest protects and 2 cameras disconnect from the nest services. They were still on my wifi networks, i could see the dns requests hitting the firewall and a single http request, but that http request never got a response from the nest cloud. I figured out that my firewall had a bad entry in its dns cache for the nest cloud. Once i disabled the dns cache option on the firewall everything came back to life. Just thought i would post the solution here. Thanks, michael
