The error message suggests there was a problem running
curl. Could you try running the following command on your server to check whether
curl works when it's run manually?
/opt/bitnami/common/bin/curl --verbose --location --silent --get --request GET "xxx.xxx.xxx.xxx"
You also mention you created an instance from a snapshot. Did you find the same issue on the instance where the snapshot came from?
Thank you for your kind cooperation.
