I am using Powershell a lot at work to access SharePoint. All of a sudden I am getting an error connecting saying DTD issue.
Now after googling it I find this:
Is it a DNS issue? It’s always a DNS issue, isn’t it!
Connecting to Microsoft’s datacenters might be trickier than you’d think. Interwebs is filled with stories about Microsoft just returning unresolvable DNS entries, which messes up the script, or your ISP might be trying to help and just makes the issue worse (by offering a “DNS help”-page which just omits the actual exception)
This might be fixed with changing to Google’s DNS (22.214.171.124), adding new entries to hosts file, disabling ISP or router features or just simply running the program/script somewhere else – try Azure virtual machine, for example.
It’s not DNS messing up? Then maybe it’s IPv6!
This was weird, butdisabling IPv6 finally solved our issues
But I don't know how to do this on the Virgin Hub 3
