physionet cert is self-signed - which is interrupted by security VPNs

[renato-umeton]

Security-focused VPNs, like Cloudflare Warp, will intercept that physioned is subject to MITM attacks because the certificate chain contains a self-signed cert. Suggestion is to switch to switch to letsencrypt with routinely updates certs CI like acme.sh
