Today, I have this issue, that i could not connect to a webservices, that are hosted by the Danish Tax Service, the URL where: https://emcstest.skat.dk
I got this warning:
|
1 |
Invoke-WebRequest : The request was aborted: Could not create SSL/TLS secure channel. |
When running these commands
|
1 2 |
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12 $WebResponse = Invoke-WebRequest "https://emcstest.skat.dk" |
No matter what I did. But final I tested the webpage against SSLLabs
https://www.ssllabs.com/ssltest/analyze.html?d=emcstest.skat.dk
Found these ciphers
I then run these commands:
|
1 2 3 4 5 6 7 |
Enable-TlsCipherSuite TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 Enable-TlsCipherSuite TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 Enable-TlsCipherSuite TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256 Enable-TlsCipherSuite TLS_AES_256_GCM_SHA384 Enable-TlsCipherSuite TLS_AES_128_GCM_SHA256 Enable-TlsCipherSuite TLS_CHACHA20_POLY1305_SHA256 Enable-TlsCipherSuite TLS_AES_256_GCM_SHA384 |
And finally I where able to access the webpage though powershell.
