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

    Hi, hoping someone can help?

    Every now and again, I'm getting the following error:

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

    which relates to var tweets = uTwit.GetLatestTweets(config, numberOfTweetsToDisplay, includeReplies, includeRetweets)

    Wondering if anyone else has had this?



    p.s using Umbraco v6.1.6 on Windows Server 2012

    I am having the same problem with 7.6.1

    2017-08-31 17:55:54,055 [P4608/D2/T68] ERROR Umbraco.Web.Scheduling.ScheduledPublishing - Failed (at "").

    According to this link The request was aborted: Could not create SSL/TLS secure channel some suggest to change App Pool Identity in IIS to LocalSystem from NetworkService but that did not help me.

    Anyone has managed to solve this problem?

    Whe have a same sort of problem. I'm going to try out the following line of code just before the call

    System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls; // comparable to modern browsers

    I've just fixed this on a bunch of sites, two of which had uTwit installed and suffered from this same problem. See my solution here:
