It looks like error #5161 usually happens when Vinchin Server can’t properly connect to the AWS platform. This may be due to unstable network or wrong settings (Account Type, Access Key, Secret Key). You can try checking the network by pinging ec2.us-east-1.amazonaws.com (replace with your region if needed), and make sure the Account Type, AK, and SK are correct. After that, try adding the AWS platform again and it should work.
