My lynx: Lynx Version 2.8.9dev.11 (15 Nov 2016) libwww-FM 2.14, SSL-MM 1.4.1, GNUTLS 3.5.6, ncurses 6.0.20161126(wide) On: Linux Phenom-II-x6 4.17.8dav1 #5 SMP PREEMPT Thu Aug 9 03:50:23 UTC 2018 x86_64 GNU/Linux has the same problem. Using curl or changing the user agent header fixes this. Your experience goes to show how broken the web site is, not even returning the correct response code for the web server's refusing to allow your user agent access.

With lynx, I see an immediate (on human timescales) HTTP/1.1 504 GATEWAY_TIMEOUT response. With my own manual fetcher script, I see a redirect to HTTPS. I infer they are playing silly User-Agent: games. Maybe telling lynx to lie in its User-Agent: header would work around whatever is broken? Gateway Timeout _is_ the standard meaning of 504: "The 504 (Gateway Timeout) status code indicates that the server, while acting as a gateway or proxy, did not receive a timely response from an upstream server it needed to access in order to complete the request.". I suppose it's possible that lynx requests get redirected to a backend that's timing out. But the short time before I get the 504 argues against that. Without transparency into the server setup behind it, it's difficult to say more.

Re: [Lynx-dev] Why Do I Receive a Gateway Timeout on www.crisisgroup.org
Actually, no it does not. The profile at the top of this page, the one which appears in lynx, when you remove the user header indicates the servers are rather simple, its dated 1999. if you go to the site with lynx and get the 504 gateway error, change the send user agent header and the site displays, oddly but it displays. links uses a different approach to user agent headers. when I researched the error, all information indicates it is a site thing not a you thing.

hi Chime, Normally 504 gateway errors have nothing to do with your personal setup. Instead they reflect a communications error between the site's own servers, timing out communications wise. have you been able to reach the site before using lynx? kare On Mon, 20 Aug 2018, Chime Hart wrote: Well Russell, thanks for looking, however, whether I try here on Shellworld or on my hard-drive in Debian, I receive a 504 error.

Quoth Chime Hart: 'in trying to visit www.crisisgroup.org l i n k s does reach this site, but when going to specific articles, I think it just loops around. But worse, L Y N X gives me a 504 gateway timeout. Can some1 please examine, incase there are work-arounds.' I have no trouble connecting. The pages are > 100K, if size matters. Every page begins with > 300 lines of header information before the information on the topic. If you're being read to you have a lot of the same being read before you get to the information you want. russell bell ___ Lynx-dev mailing list Lynx-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/lynx-dev
