我试图用gevent.pywsgi.WSGIServer包装Flask应用程序。一切正常，但是，当我尝试为ssl添加密钥和证书时，它甚至无法再接受任何客户端。

这是一个引发错误的简单示例：

from gevent.pywsgi import WSGIServer
from flask import Flask

app = Flask(__name__)
app.debug = True

@app.route('/')
def index():
    """
    Renders the homepage.
    """
    return render_template('index.html')

if __name__ == "__main__":
    app.config["SECRET_KEY"] = "ITSASECRET"
    http_server = WSGIServer(('localhost', 5000), app, keyfile='key.pem', 
certfile='cert.pem')
    http_server.serve_forever()

这是错误的堆栈跟踪：
