node-v:16.14.0

i'm not using proxy and i have tried every single solution on the inte.net and still have the same error

also have tried every solution in this thread: npm not working - "read ECONNRESET"

Here are the last lines of my log file that I think indicate the problem:

See: https://www.jhipster.tech/configuring-a-corporate-proxy

Use these commands:

npm config set proxy http://username:password@host:port
npm config set https-proxy http://username:password@host:port
