当我尝试在Coursera中提交我的在线作业时,它显示以下错误(尽管我确实曾与导师联系,他们建议关闭防火墙,但是它没有帮助,我也尝试过VPN,但再次失败了,用Google搜索但仍然没有任何进展) )
Failed to connect to www-origin.coursera.org port 443: Timed out
[error] submission with curl() was not successful
Function: submitWithConfiguration>validateResponse
FileName: C:\Users\Dhruv\Desktop\ML octave\machine-learning-ex1\ex1\lib\submitWithConfiguration.m
LineNumber: 158
function response = validateResponse(resp)
% test if the response is json or an HTML page
isJson = length(resp) > 0 && resp(1) == '{';
isHtml = findstr(lower(resp), '<html');
if (isJson)
response = resp;
elseif (isHtml)
% the response is html, so it's probably an error message
printHTMLContents(resp);
error('Grader response is an HTML message');
else
error('Grader sent no response');
end
end
请帮助

好奇怪,
我发现,以前我是使用我的学院网络提交作业的,但是当我使用移动数据时,我可以提交作业。我想我的学院网络必须受到一些限制。
