Use NPM at a Synology NAS

[tobylibo]

When I set npm as a reverse proxy for Synology NAS, I encounter the following issue:

I can't log in to Synology NAS page from my iPhone using Safari or Edge.

Enter your username、password, and two-factor authentication, and tell me "Your login is invalid, Please sign in again."

But I was able to sign in successfully on my Computer (PC and Mac) or iPad. I don't know if anyone has the same issue as me. Or it can help me.
