Resolving Amazon Echo registration error 10:2:5:60:1
When trying to register a new “Amazon Echo” into my home network, I received the following error:
“There was an error registering your device. Visit Help for troubleshooting tips. Error 10:2:5:60:1”
I followed all of the usual steps (reset device, reset router, uninstall/reinstall mobile app, etc.), but nothing worked. I also setup a second Wi-Fi network to see if that was the issue.
I should point out that I already had another working Amazon Echo Dot device that was previously setup and still working on the same WiFi network that didn’t have any issues registering. I also took that offline to ensure that wasn’t an issue.
I then removed all other WiFi devices from the network. It still didn’t work.
I called Amazon support. They were great, but it still didn’t work. So they sent me a new one and received it in two days. They’re awesome.
What wasn’t awesome was that the new device had the SAME ERROR! So now I know it IS the network.
What I found was that with all devices off of the network, I check the logs (Advanced > Logs) on my Cable Modem device (Netgear c6300, Firmware V2.01.14) that I saw that the device was reporting a DoS attack that were coming from the Echo device. Below is the error I saw:
[DoS attack] Port Scan PROTO:UDP SPT:50395 DPT:123
The firewall didn’t have any restrictions on the devices that could be on the network, nor blocking outbound traffic, so this was weird. I found a setting to ignore this type of traffic and not block it. I crossed my fingers and gave it a try.
First, login to your device (typically http://192.168.0.1/ ), then click on the “Advanced” tab. Click “Setup” in the left menu, then click on “WAN Setup”. Enable the Checkbox for, “Disable Port Scan and DoS Protection”, then click “Apply”.
Once your device has reset, then go through the normal setup process using Amazon Echo. Now your Echo should be working. After it’s working, go back into your Netgear setting and disable the setting we applied earlier. Afterward, the Echo should still work AND you’re protected from Port Scan and DoS protection.
I hope this helps you in your situation.

I had this problem and went to help and got into a third party website. They tried to sell me a $500 network protection package. The took over my computer and told me my network had been compromised and I needed to pay them to fix it. They installed some malware on my computer. I had to have it scrubbed.
To fix this problem, use a paperclip and push it into the hole on the bottom of the device. The ring will turn orange/yellow then blue. Go to your Alexa app and set your device up like it is new and reregister it.
I ran into the same issue after a short power outage. I tried over and over but got the same error message. Frustrating! As a last resort, I unplugged my Echo for about a minute. When I plugged it back in, it was connected to my home network! Maybe I got lucky, but I wanted to pass my “fix” along just in case it could help someone else.
