The reason why the new novel kept getting an ahaha error after logging in was probably due to network connection problems or server response problems. An ahaha error is a network error, usually indicating a network connection interruption or a server failure. This kind of error would usually cause the program to stop responding or loop indefinitely. To solve this problem, try logging in again or checking the network connection. If the network connection is normal, you can try to clear the browser's buffer or reload the webpage. If there is still a problem, you can try to contact the website administrator or try to use another browser to access it.
