我已經使用 Nginx、supervisor 和 gunicorn 在 AWS ubuntu ec2 中部署了我的 Flask Web。一些奇怪的地方： (1) 有時我在safari瀏覽器中可以通過域名訪問我的網站，但一段時間后，我無法通過域名訪問它。域名（test.com）訪問的站點圖片如下：
test.com
parked free, courtesy of GoDaddy.com.
(2) 我可以使用所有瀏覽器通過 IP 地址訪問它。
(3) 有時我試過其他瀏覽器，可以通過域訪問。但經過一段時間后，與（1）相同的問題。我的設定檔案如下：
須藤vim /etc/nginx/sites-available/default
server {
listen 80 default_server;
listen [::]:80 default_server;
# SSL configuration
#
# listen 443 ssl default_server;
# listen [::]:443 ssl default_server;
#
# Note: You should disable gzip for SSL traffic.
# See: https://bugs.debian.org/773332
#
# Read up on ssl_ciphers to ensure a secure configuration.

# Self signed certs generated by the ssl-cert package
# Don't use them in a production server!

uj5u.com熱心網友回復：
我已經解決了！剛剛洗掉了godaddy帳戶域名設定中的停放值DNS設定。這可能會導致上述問題。
