I woke up to my Homey offline today. I tried pulling the power and pulling back in and that didn’t work. I used the USB recovery tool and installed the latest firmware, which was successful, but I still couldn’t connect. I factory rest Homey Pro and added it back into my account which worked but when I reinstalled my backup it went right back to giving the “failed to handshake” error. I factory reset again and installed the oldest backup I have, still getting the error.

Any Ideas?

Connected via Wifi or Ethernet ? Did your Homey get IP address ? PINGing it, any results ?

…what does the Athom support say about that ?

You can try also reaching out to this user, how he resolved that.

> I got an odd error today. Suddenly I couldn’t get access to the Homey neither with the app nor via the Web. I got the message: “Failed to handshake client” Have restarted Homey Pro (former version) by removing the cable, but still the same issue. Could anyone help me what to to? If removing the Homey and try install it again, will that help? And can I then load the backup that Homey performs every day?

Thanks for the reply @Sharkys. It is connected via Wi-Fi. I did reset my Wi-Fi router and it didn’t work. Homey is getting an IP and to make sure it wasn’t trying to reuse an IP already assigned, I created a static IP for it and reset it, when it restarted it grabbed the new static IP I assigned it in my router, so it is definitely connecting to Wi-Fi. I have pinged it from a computer on my network and the pings go through. I haven’t reached out to support yet. I was hoping that someone here had an idea for me to try before I reached out.  
Oddly, it randomly connected for a few minutes and my ZigBee and Z-Wave networks came back online and my light switches started working again and I could control Hue through Matter, then it all stopped working and the app couldn’t connect again and my z-wave, zigbee, and matter stuff went offline again. I feel like it isn’t just a Wi-Fi connection issue because I should still be able to send local commands from a zwave light switch through the hub to another local zwave device without internet, and that isn’t working.

I just reached out to support and their turn around time is 1-2 weeks, kind of ridiculous! I also reached out to the other user having the same issue to see how/if they resolved it.

They sometimes answer sooner, mainly for warranty type of questions.

Btw, what is the LED ring color,when that happens? Rainbow or some other? It’s really weird issue

So, I have it set to off. So, it is off. When I plug it in, it is white spinning. Most times it just goes off a few times I have gotten a red flash after the white spinning stopped. If I don’t touch it, it resets itself after about 5 minutes and I get white spinning again.

That means that your Homey is crashing, actually the Docker Container of Homey. How many apps you have installed, eg. \<50 or more? Have you tried to disable some apps upon start,eg. during that short duration it’s available?

I have 18 apps. So, it just came back up and is working again almost 12 hours after it stopped working. There are two apps that turned themselves off, one was a weather app the other was Zone Activity. The weather app I wasn’t really using so I uninstalled it. I do use the Zone Activity app, I wonder if I should find an alternative. Maybe these were causing the crash. I just find it odd that it came back online all by itself once I stopped playing with it for a few hours and that two apps stopped working once it came back on.

Maybe worth trying a new power supply. I’ve had two go a bit off

@Philip_Montgomery, I’ll definitely try that! Wehn I was doing the USB recovery I had it plugged into my computer and it was still having issues, but I was using the same USB cord, I should just switch out the whole adapter and cord.

You can try also the cable and power adapter, but beware - that adapter must supply 5.2V and some amps - don’t recall exactly, however computer USB port is not sufficient.

Also, if there would be some problem with adapter, you would see under voltage errors here - [Homey Developer Tools](https://tools.developer.homey.app/tools/system)

Eg. must be like this if all is OKay and it’s not Power supply issue :
