Issue is with this self.wfile.write(message) line

from http.server import BaseHTTPRequestHandler, HTTPServer
class WebServerHandler(BaseHTTPRequestHandler):

def do_GET(self):
    try: 
        if self.path.endswith("/hi"):
            self.send_response(200)
            self.send_header('Content-type', 'text/html')
            self.end_headers()
            message = ""
            message += "<html><body>Hello!</body></html>"
            self.wfile.write(message.encode('utf-8'))
            print (message)
            return
    except IOError:
        self.send_error(404, 'File Not Found: %s' % self.path)


def main():
    try:
        port = 8080
        server = HTTPServer(('', port), WebServerHandler)
        print ("Web Server running on port %s" % port)

        server.serve_forever()
    except KeyboardInterrupt:
        print (" ^C entered, stopping web server....")
        server.socket.close()

if __name__ == '__main__':
    main()

here is my code I want to open a server on the localhost:8080.

from http.server import BaseHTTPRequestHandler, HTTPServer
class WebServerHandler(BaseHTTPRequestHandler):

    def do_GET(self):
        try: 
            if self.path.endswith("/hi"):
                self.send_response(200)
                self.send_header('Content-type', 'text/html')
                self.end_headers()
                message = ""
                message += "<html><body>Hello!</body></html>"
                self.wfile.write(message)
                print (message)
                return
        except IOError:
            self.send_error(404, 'File Not Found: %s' % self.path)


def main():
    try:
        port = 8080
        server = HTTPServer(('', port), WebServerHandler)
        print ("Web Server running on port %s" % port)

        server.serve_forever()
    except KeyboardInterrupt:
        print (" ^C entered, stopping web server....")
        server.socket.close()

if __name__ == '__main__':
    main()

And when i'm open the server i'm supposed to get a white web page with the word "Hello!" wrote on it.

But when i open the page i have a white page and on my terminal i have this :
