Notification: login attempt failed

Good afternoon

This message that I indicate below has already appeared twice in one week in Notifications:

Login attempt failed
Login attempt or request with invalid authentication from xx.xxx.xxx.xx.amazon.com (xx.xxx.xxx.xx). See the log for details.

I don’t know if I should worry about this. Could it be an attack on my home assistant server? Nothing appears in the log…
Please could you help me? Thank you.

Hard to say for sure as you removed the ip address.

The first day: 54.240.197.51 amazon.com
The second day: 54.240.197.18 amazon.com
I thought the IP addresses could not be put in the forum …

Sure they can. Just don’t ever post your public IP address. IP addresses on your local network are ok too, as they can not be routed over the Internet.

Do you have an Alexa device or some other Amazon cloud service?

They both are genuinely their cloud servers.

Thanks for your interest in answering my question
Hire Amazon aws to use Alexa in HA. I performed a series of tests to see if it worked well and then deactivates it. Right now I don’t have it in use, but maybe the account has continued to call Amazon service (AWS) … ??
In any case, in the near future I want to activate AWS to use Alexa in HA.

Yeah that’s what it is.
