Failed to invoke web service: The request was aborted: Could not create SSL/TLS secure channel

(0) ShareShare
ReportReport
Posted on by Microsoft Employee

In the past I've successfully called APIs using Invoke web service action, but some APIs give this error and fail to make a call.
I can't seem to find any differences between them and I couldn't find any information related to Power Automate Desktop and this error. Only clue I have is the same error from C# forums https://stackoverflow.com/questions/2859790/the-request-was-aborted-could-not-create-ssl-tls-secure-channel where security policy seems to be the problem. But I don't see how I can change it in Power Automate Desktop.

 

Has anyone ran into this or a similar problem?

Any clue to lead me on the right path would be helpful.

 

Full error details:

The request was aborted: Could not create SSL/TLS secure channel.: Microsoft.Flow.RPA.Desktop.Modules.SDK.ActionException: Failed to invoke web service: The request was aborted: Could not create SSL/TLS secure channel.. ---> System.Net.WebException: The request was aborted: Could not create SSL/TLS secure channel.
