I want to push my commits to a Bitbucket repository but this error occurred:
Fatal: unable to access 'https://[email protected]/myUsername/myRepository.git/': Unknown SSL protocol error in connection to bitbucket.org:443
(Source – Techuz) So when you get SSL connection error, it means the internet connection on your phone is preventing the browser from loading the page for security and privacy.
You can get more information with
# Windows set GIT_CURL_VERBOSE=1 set GIT_TRACE_PACKET=2 # Unix export GIT_CURL_VERBOSE=1 export GIT_TRACE_PACKET=2
And then try a git push
.
Double-check your proxy settings if you have one.
Note: git 2.8 (March 2016) adds more information on an error 35:

remote-curl
: includecurl_errorstr
on SSL setup failuresFor
curl
error 35 (CURLE_SSL_CONNECT_ERROR
) users need the additional text stored inCURLOPT_ERRORBUFFER
to debug why the connection did not start.
This iscurl_errorstr
inside ofhttp.c
, so include that in the message if it is non-empty.
Also check out the common causes for that message:
If it was working before, and not working today, it is possible the SSL private key has expired on the BitBucket side (see below, reason #3), but that doesn't seem to be the case here (the certificate is valid until 12/03/2014).
Firing off a request like the following, results in the Unknown SSL Protocol error:
curl --sslv2 https://techstacks-tools.appspot.com/
Why? Well, in this case it is because the techstacks tools site does not support SSLv2, thus, generating the curl (35) error.
You could be trying to connect to the site using an ssl cipher that the site is configured to reject.
For example, anonymous ciphers are typically disabled on ssl-encrypted sites that are customer-facing. (Many of us set a blanket rejection policy on any SSL-encrypted web site—regardless of it's purpose.)
The following command string "can" also result in the curl (35) error:
curl --ciphers ADH-RC4-MD5 https://some_web_site.some_domain.com/
Unfortunately, the type of error response you can get from curl depends largely upon the ssl server. On some sites, you'll receive the Unknown SSL Protocol error but on my techstacks-tools site, I get:
curl: (35) error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure
Kudos to Google because this particular error is a bit more descriptive than the one my websites at work generate because this at least tells you that a ssl socket was started but because of handshake failures, the socket was never able to complete.
Try connecting to the site with a cipher that the site supports. Not sure which cipher to use? Well, let me introduce my cryptonark ssl cipher tester...
I came across this one earlier today working with an old WebSeAL site.
In IBM GSKit, you can specify how long the private key password is valid. After reaching a certain date, you will still be able to get webseal started and listening on port 443 (or whatever you set your https-port value to) but you will not be able to successfully negotiate an SSL session.
In today's case, the old WebSEAL instance was using long-expired kdb file with a long expired private key password. Once replaced with the correct, more-up-to-date version, everything worked again.
Some ISP's and DNS providers like to intercept your failed DNS queries in order to redirect you to a search engine results-style page offering you alternative URLs or "Did you mean...?" counter-query results.
If you see an error like this:
error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol,
it could be due to you typing the hostname incorrectly or the hostname is not yet tabled in your DNS. You can verify that with a simple "
host
" or "nslookup
".
Note (August 2015): Git 2.6+ (Q3 2015) will allow to specify the SSL version explicitly:

http.sslVersion
The SSL version to use when negotiating an SSL connection, if you want to force the default.
The available and default version depend on whether libcurl was built against NSS or OpenSSL and the particular configuration of the crypto library in use. Internally this sets the 'CURLOPT_SSL_VERSION
' option; see the libcurl documentation for more details on the format of this option and for the ssl version supported.
Actually the possible values of this option are:
- sslv2
- sslv3
- tlsv1
- tlsv1.0
- tlsv1.1
- tlsv1.2
Can be overridden by the '
GIT_SSL_VERSION
' environment variable.
To force git to use libcurl's default ssl version and ignore any explicithttp.sslversion
option, set 'GIT_SSL_VERSION' to the empty string.
