英文:
Cant start flask app using gunicorn on ubuntu server
问题
你好，我明白你遇到了问题。根据你的描述，看起来这是一个权限问题，因为端口443是特权端口，需要特殊权限来运行服务。你可以尝试以下解决方法：
-
确保你的Flask应用程序有足够的权限来绑定到443端口。你可以使用root用户或者sudo命令来运行你的应用程序，但请确保以安全的方式进行。
-
如果你不想使用root用户来运行应用程序，你可以考虑使用反向代理，比如Nginx或Apache，来代理到Flask应用程序，并允许它监听一个高于1024的端口，然后由反向代理服务器处理443端口。
-
确保你的SSL证书文件（cert.pem和key.pem）的路径和权限设置正确，以便应用程序可以访问它们。
请按照这些步骤检查你的配置，看看是否有帮助。如果还有其他问题，请提供更多信息以便我能够提供更具体的建议。

I think this is some permision stuff but not sure. I have to be honest that i dont use ubuntu server that often. Also want to mention that i NEED it to run on port 443. I was reading something about ports that are less than 1024 are privileged but actually dont know what to do with that.
(This is my first post, if is something missing just tell me i will try to provide more)

得分: 1
我做的基本上就是四处搜寻，发现在 Flask 应用中我设置了 port=443，我只是删除了它，然后它就能正常工作。
...一个月后

Okay so basicly what i did was snooping around and finding out and in flask app i had set port=443 and i just deleted and it works.
...After month
