I too was facing the same problem while setting up authentication for kibana. Here is the error in my /var/log/nginx/error.log file

2020/04/13 13:43:08 [crit] 49662#49662: *152 crypt_r() failed (22: Invalid argument), client: 157.42.72.240, server: 168.61.168.150, request: “GET / HTTP/1.1”, host: “168.61.168.150”

I resolved this issue by adding authentication using this.

sudo sh -c "echo -n 'kibanaadmin:' >> /etc/nginx/htpasswd.users"
sudo sh -c "openssl passwd -apr1 >> /etc/nginx/htpasswd.users"

You can refer this post if you are trying to setup kibana and got this issue.
