Login attempt or request with invalid authentication from remote access

Hi,

I setup duckdns, but still cannot access remotely, the logs says:

Login attempt or request with invalid authentication from x.x.x.x (x.x.x.x). Requested URL: ‘/auth/token’. (Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/104.0.0.0 Safari/537.36)

Any suggestion? I also tried nginx and no success neither
