Why?
This situation is generally caused by an error in your redirect URL.
Mainly because of encoding errors, you need to specify an encoding and parse it correctly.
In my case, the reason for this error is probably because Chinese characters are added to the URL.
My solution is:
change
return Redirect("/battle/fail?alertInfo=中文字符!");
to
string url = "中文字符!";
string encodeURL = HttpUtility.UrlEncode(url);
return Redirect("/battle/fail?alertInfo="+ encodeURL);
