Hi @shantanusingh,

This is an an issue relating to your server’s operating system – see How to force older debian to forget about DST Root CA X3 Expiration and use ISRG Root X1 - SSL certificate problem: certificate has expired - Stack Overflow for details and some pointers that should help.

The cause is a recently-expired root SSL certificate. You’ll need to update your system’s certificate list.
