Not able to use Equinix API, giving error - error:0A000438:SSL routines::tlsv1 alert internal error

This issue mostly seems like on the client side with curl or SSL versions or with respect to CA certificates on the system.

Possible causes and resolutions:

1. check Curl Version, if outdated update it

curl --version

2. check OpenSSL version, if outdated update it

openssl version

3. debug with OpenSSL to see more detailed SSL/TLS negotiation output

openssl s_client -connect api.equinix.com:443

4. Update CA certificates - ensure your system's CA certificates are up to date

sudo apt-get update
sudo apt-get install --reinstall ca-certificates

Also, curl/ssl verbose logs will give more insight.
