Changed ECDSA host key even when I didn't manually change it? Database connection error
0
Hi, when I started and stopped my lightsail instance (linux), it says "Error establishing a database connection."
Upon further investigation, I saw:
[pem file]: Please contact your system administrator.
Add correct host key in /Users/sid/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /Users/sid/.ssh/known_hosts:3
ECDSA host key for braindocacademy.com.au has changed and you have requested strict checking.
Host key verification failed.
I don't understand what's going on, and what steps I should take. I didn't manually change any keys whatsoever.
If you could assist me with this, it would be greatly appreciated.
Cheers,
Carl
Can you verify that the hostname you are using is resolving to the IP address of your instance? Host key changes can indiciate an MITM attack, so please be cautious.
