Xenu Link Sleuth has worked for years and two weeks ago it failed to connect to my site (https://www.horsekeeping.com). No changes made to my computer at that time. Xenu can connect to every other site I've tried. My browsers, email and ftp are all connecting to my site. Uninstalled and installed Xenu several times. Disabled firewalls and anti-virus, flushed DNS. Xenu consistently gives error: "busy" "no connection", when I try to crawl my own site. I'm on Hughes latest satellite and I have another similar computer on same network through a TP-Link router and Xenu will connect to my site on that computer. I discussed this problem with Xenu's developer and he says it's not a problem with the program and I agree - I don't think it's the program or the router. What on my computer would prevent Xenu from connecting only to my site?
