How To Resolve “Could Not Create SSL/TLS Secure Channel” Exception For SharePoint Online

This blog helps you resolve the "Could not create SSL/TLS secure channel" error when we try to connect SharePoint Online through PnP PowerShell

When I tried to connect SharePoint Online through PnP PowerShell by using the below command.

PS: > $cred = Get-Credential
PS: > Connect-PnPOnline –Url https://<tenant>.sharpeoint.com –Credential $cred

I have received the below error message.

Connect-PnPOnline 

The request was aborted: could not create SLL/TLS secure channel.

I have checked the code. Oh… and I had entered the URL with typo error to connect the site.

 

So, I have corrected the URL and tried to connect the site. It works fine.

PS: > $cred = Get-Credential
PS: > Connect-PnPOnline –Url https://<tenant>.sharepoint.com –Credential $cred

Root cause

This issue will rise when we provide the wrong URL.

Solution

Please check the URL once again, before running the code.
