verdaccio: npm ERR! fetch failed http://verdaccioIP/babylon/-/babylon-7.0.0-beta.0-ranges.tgz

Hi,

We have faced a following problem with our verdaccio server :

[npm install] npm ERR! fetch failed http://verdaccioIP/babylon/-/babylon-7.0.0-beta.0-ranges.tgz

After searching we found that this bug is resolved in the latest version of Verdaccio. After that, we have upgraded the verdaccio version and this problem was solved.

But After up-gradation, we are not able to see OLD packages on UI. After publishing, we can see that particular package on UI, but not before that.

We cannot publish every package again.

Could you please let us know, how we can solve this problem.

Thanks & Regards D.Singh
