Happened a few times before I got frustrated enough to look it up.<br><strong>The problem is Kaspersky.</strong><br>Kill Kaspersky.<br>Problem solved.<br><img class="alignnone size-full wp-image-2535" alt="kaspersky-bugs" src="https://cdn.joejiko.com/wp-content/uploads/2013/03/kaspersky-bugs.png" width="244" height="244" /><br>I'd also like to take the time to recommend an alternative: <a href="https://www.bitdefender.com/" target="_blank">BitDefender</a><br>The interface is clean. The software is intuitive. Oh yeah, and I haven't had any malware problems or strange 103 issues.<br><strong>Update</strong>: I've since uninstalled bitdefender because it sometimes bans "unsafe websites" and there's no override. Only way to get past the block is by uninstalling.<br> <br><strong>TL;DR</strong><br>The problem seems to only occur on larger sites that use multiple servers.<br>Depending on the IP you get, sometimes the browser doesn't like something in its HTTP headers.<br>More likely than not, it's an anti-virus/internet security software issue.<br>So if you don't have Kaspersky,<br>first find out what AVP (anti-virus program) you have,<br>then disable it.<br>Refresh the 103 error page.<br> <br><strong>Update</strong>: Saw a <a href="https://productforums.google.com/d/msg/chrome/HEfvBmJkTsI/Rq_MLgEc8B0J">google groups post</a> 3/12 that says Kaspersky has a patch out for this.<br>"Patch 17 - for Chrome"<br>Whatever that means..
