Github is currently working for me via Hughesnet.   I tried the github-debug dot com diagnostics again, and these two errors still occurred, so I guess they are irrelevant.     @cm7 wrote:   Two errors that stood out to me were: - The ssh git clone test also said "The authenticity of host '[github dot com]' (140...4) can't be established." - A ping test from some github host to my ip address said "Destination Net Unreachable".  [this was the 184.xx.xx.xx public ipv4 address which as MarkJFine pointed out, might not work from behind a NAT (network address translation) router, either hughesnet's or github's.]         ...

When I'm on hughesnet and ask a search engine "What's my IP address" it gives me a 184.xx.xx.xx number (dynamically assigned, may be different on different days).   That's same number that the web page on github-debug dot com retrieves in its tests. It is the same number the github-debug dot com diagnostic is trying to ping when it reports "Destination net unreachable".   If I try to ping the same number, I also get "Destination net unreachable".   That "184.xx.xx.xx" number does not appear in any tracert that I've run.     ...

I have not seen problems when I ping github dot com or tracert github dot com (via hughesnet), it always responds. ... View more

I have also been having trouble communicating with github while other sites work fine. Github has been responsive for me through other routes when it is unresponsive for me through hughesnet. Usually the browser times out. Occasionally it says "The page you are trying to view cannot be shown because the authenticity of the received data could not be verified."   Github has some bidirectional network diagnostics at github-debug dot com. I can't tell if the problem is in equipment of github, hughesnet, or someone in between. I tried to post a redacted message showing my results for you to compare, but it was flagged as spam.   Two errors that stood out to me were: - The ssh git clone test also said "The authenticity of host '[github dot com]' (140...4) can't be established." - A ping test from some github host to my ip address said "Destination Net Unreachable".       ...

[Previous post was rejected without explanation, maybe automatic rejection due to links to specific github sites even though they are relevant to this problem?  I've removed the links and spelled out site names]   The problem appears specific to github and hughesnet.  Other sites are working fine for me via hughesnet (e.g., gmail).  Github works fine for me via DSL. Communciations with github via hughesnet is not working reliably for me, often the browser times-out just loading a repository page. Ping and tracert show github dot com is reachable via hughesnet, however. I have accessed github dot com through DSL, and github dot com works fine for me through the DSL, so github dot com servers are responding. I have accessed github dot com from DSL in different locations, so I don't think anything about github dot com is specific to route or ip address.   Sometimes loading a github dot com page aborts with the error: "The page you are trying to view cannot be shown because the authenticity of the received data could not be verified." (Right now even help pages are not loading, though ping to help dot github dot com works)   When trying to clone a repository through hughesnet, I'm getting "fatal: TaskCanceledException encountered.".  (The same command works through DSL.)   githubstatus dot com is currently reporting "All systems operational". Github help (help dot github dot com, Getting started with Github, Troubleshooting slow downloads and connectivity problems) says they are not responsible for congestion outside of github, and links to github-debug dot com.   github-debug dot com is a web page with diagnostics for users to run, and reports diagnostics from their servers back to the client. (Submitting the github contact form linked from github-debug failed when I tried through hughesnet.  I did submit the contact form via DSL with the hughesnet data, but there has been no response, automated or otherwise, so I don't know if it was received.)   My results are something like the following (ip address and keys [elided], the [184....] is apparently my ip address).  I highlighted a couple errors that stood out to me in red.  Do these diagnostics help locate whether the problem is in equipment of github or hughesnet or someone in-between?   Command line diagnostic commands (from github-debug dot com)   git clone [https ://github dot com/github/debug-repo] debug-repo-http Cloning into 'debug-repo-http'... remote: Enumerating objects: 1649, done. error: RPC failed; curl 56 OpenSSL SSL_read: Connection was reset, errno 10054 fatal: the remote end hung up unexpectedly fatal: protocol error: bad pack header git clone [git at github dot com] :github/debug-repo debug-repo-ssh Cloning into 'debug-repo-ssh'...
