We currently have the effect that when clicking Open with explorer in a document library we can't add / edit / change items. The folder opens but as soon as we try to add something the explorer.exe freezes. Same goes for mapping a library to a drive letter.
By default we access our intranet via http. About a year ago we added the option to access it via https. And when accessing our Intranet via https everything works fine.
Anyone else has this feature/bug? Is there a way to fix it (a patch that might have been responsible)?
We use SharePoint 2013 on Windows Server 2012 R2. Client OS is Windows 10.
Edit2: We just got hold of a laptop without the latest patches and the behavior is the same. So our Patchday wasn't the issue here.
Edit3: We tried rewriting the URLs through our KEMP load balancer but the result is a 'broken' intranet due to the hard links.
