ERROR: GitError(Code:ERROR, Class:OS, failed to send request: A connection with the server could not be established )

I’m trying to install Pkg.add(“DataFrames”) but I get the following message. Any idea what could be the problem?

Looks like a network glitch. Check that github.com is reachable, eg with ping, then try again.

The error message seems different from what the “easy fix” fixes.

[bernhard]

I think you are correct. I deleted my post.

[Chasqui]

Thank you for your response. I tried ping and it seems that I have connection with gitbub.com
I tried again Pkg.add(“DataFrames”) and I got the same error message.

Follow the manual fix in this post, not the “easy fix”

solution

Errors for Git / Pkg

Finally got a fix. The Easy fix on this page didn’t cut it. Update to enable TLS 1.1 and TLS 1.2 as default secure protocols in WinHTTP in Windows The quick-fix didn’t patch the Webio.dll and the Winhttp.dll in the Windows-folders. So I went to the update-catalog and downloaded the proper file for my system: Microsoft Update Catalog Patched,restarted, works.

I’m reviving this post.
I’m on windows 8 and the proposed solutions do not work for me.

In the list given at https://www.catalog.update.microsoft.com/search.aspx?q=kb3140245 , none of the updates seem to apply to windows 8. I updated to .Net 4.5, but to no avail.
I would really appreciate some help.
Many thanks in advance
Olivier

I would try either this:

Update für Windows Embedded 8 Standard für x64-Systeme (KB3140245)

or this:

Update für Windows Embedded 8 Standard (KB3140245)

depending on your system (32/64 Bit Version).
The quick fix didn’t work for my systems, hence the workaround for a manual patch. I don’t know what the patches do in particular, but the registry hacks in the kb-article didn’t succeed either:

Thanks for your reply.

Unfortunately KB3140245 does not work.

I don’t see any other options.
I will contact my system administrator.
