Powershell Invoke-WebRequest Fails with SSL/TLS Secure Channel
I’m trying to execute this powershell command
Invoke-WebRequest -Uri https://apod.nasa.gov/apod/
and I get this error. “Invoke-WebRequest : The request was aborted: Could not create SSL/TLS secure channel.” https requests appear to work (“https://google.com”) but not this one in question. How can I get this to work or use other powershell command to read the page contents?

try using this one
In a shameless attempt to steal some votes, SecurityProtocol is an Enum with the [Flags] attribute. So you can do this:
Or since this is PowerShell, you can let it parse a string for you:
Then you don’t technically need to know the TLS version.
I copied and pasted this from a script I created after reading this answer because I didn’t want to cycle through all the available protocols to find one that worked. Of course, you could do that if you wanted to.
Final note – I have the original (minus SO edits) statement in my PowerShell profile so it’s in every session I start now. It’s not totally foolproof since there are still some sites that just fail but I surely see the message in question much less frequently.
