npm SSL unknown protocol error
npm ERR! Error: 7684:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol
npm tried to speak SSL to an endpoint that was not actually serving SSL, which usually points to a proxy or registry configuration problem.
Observed message
npm ERR! Error: 7684:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol
Why it happens
- npm is connecting to an unencrypted endpoint as though it were HTTPS.
- Proxy settings are incorrect for the current network environment.
- Registry SSL configuration does not match the actual endpoint.
How to fix it
- Review npm proxy and registry configuration.
- Configure the appropriate CA or CA file for the proxy if one is required.
- Avoid disabling strict SSL unless you fully understand the network risk and temporary need.
