I am experiencing similar challenges. In my case, it is not a problem locally and only occurs in CI with GitHub Actions. I use @gsap/business, so I don't use gsap-bonus.tgz, but have it installed with a token in the .npmrc file.The following error occurred.
Run npm install
npm ERR! code ECONNREFUSED
npm ERR! syscall connect
npm ERR! errno ECONNREFUSED
npm ERR! FetchError: request to https://npm.greensock.com/@gsap%2fbusiness/-/business-3.11.3.tgz failed, reason: connect ECONNREFUSED 104. 131.8.206:443
I also tried regenerating a new token, but the error with CI remained the same. It works fine locally.Translated with DeepL
