Could not create SSL/TLS secure channel

Question asked by ronald van den berg on Feb 12, 2020

I'm using a powershell script from a monitoring tool to query ssllabs. Since a few weeks i see this error:

The request was aborted: Could not create SSL/TLS secure channel.

 

Since there was a load issue in december i've decided to wait a while to see if it got fixed but it still gives me the error which made me think the cause can be on my side.

As a test i copied the script to run from another server over another ip address and over there i constantly get the error 529, service overloaded, so well maybe it's busy but the script seems ok.

 

I can resolve and connect to the api, if i request the page from the same server as the script is running from i get this which all seems to be fine:

 

https://api.ssllabs.com/api/v3/info 

engineVersion    "2.1.0"
criteriaVersion    "2009q"
maxAssessments    25
currentAssessments    0
newAssessmentCoolOff    1000

 

What can be the cause of the error: Could not create SSL/TLS secure channel.?

Gr,

Ronald
