<div class="markdown_content"><p>Hi,<br/> thank you for reporting this!<br/> We will solve this a.s.a.p.<br/> This is a 3.5SP5 issue where a fix Setting for SSL is set.<br/> so for 3.5SP5 Users at the moment the download of libs and update packages does not work.<br/> So if possible an update to current CODESYS Version will solve it too.</p> <p>BR<br/> Edwin</p></div>

<div class="markdown_content"><p>Ok, this looks like some security-related issue with encryption, certificates and other stuff. The easiest workaround is to disable secure connections to CoDeSys Store in the AppData/Roaming/CoDeSys/CoDeSys.opt file by replacing <a class="" href="https://store.." rel="nofollow">https://store..</a>. with <a class="" href="http://store.." rel="nofollow">http://store..</a>.</p> <p>I'm not sure what causes it on my side as I've tried three different PCs (including one laptop that I know worked fine in September and wasn't touched since then until today) and two different ISPs.</p> <p>What makes me really suspicious of problems on the server side is this warning in Chrome:</p> <p>Also, the Fiddler app somehow makes the "Download missing libraries" feature work when set to decrypt (recrypt?) HTTPS traffic. So, that's another workaround.</p> <p>And by the way, here's how unsuccessful download attempts look in Wireshark:</p> <p><img alt="IMG: security.png" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=1482"/></p> <p><img alt="IMG: wireshark.png" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=1483"/></p></div>

<div class="markdown_content"><p>Well, I've disabled firewalls on two different PCs (Win8/Win10) and tried two different ISPs. Still, it shows "Download failed" after "Pending..." for about 1 sec. Could that be an older version (mine is 3.5 SP5) issue? Should I try updating it?</p></div>

<div class="markdown_content"><p>This must be an issue of Firewall Settings or other protections methods. I just tried it again myself and it worked properly. A direct access to the URL is not intended.</p></div>

<div class="markdown_content"><p>Why did the "Download missing libraries" feature stop working?</p> <p>I've tried visiting those URLs in a browser and they all seem to be "Forbidden".</p> <p>Why?
