Certifcate error while trying to use SSL/TLS

[chiranjivSharma]

I followed the youtube OneM@M tutorial for enabling SSL/TLS, in Mobius deployed in my local PC.After adding server.crt,ca.crt,server-key.pem file in Mobius root directory,if I run Mobius.js ,it gives below mentioned error

_E:\Mobius-master>node mobius.js
node:internal/tls/secure-context:69
context.setCert(cert);
^

Error: error:0A00018E:SSL routines::ca md too weak

}

Node.js v18.16.0_

Can anybody guide for any workaround?
