The first thing to do is to check the site and the certificate to find out if it is OK or not. If you are sure that it is OK then you could use the --no-check-certificate option to wget to force it... [by TrevorH]
I am trying to generate static site, I have perl script that wget the url, so the problem is sometimes wget has 500 internal error, this is failing to get that page. So I am thinking of retrying that url with 500 response.
system $command = 'wget ... -i inputfile -o outfile"
Is there a way we can capture the response and retry it or any option within wget to retry after timeout?
