Sourcetree: how to accept a self-signed cert in Windows?


I'm moving my company's code repository from SVN to Git. I've set up Stash 3.3.1 behind a load balancer that's serving a self-signed cert. No matter what I do, I cannot get Sourcetree on Windows to accept the cert. The failure I get is as follows:

"The underlying connection was closed: Could not establish trust relationship for SSL/TLS secure channel."

I've tried putting in GIT_SSL_NO_VERIFY as a system variable and inside the .gitconfig of GitBash:  no luck on either. I've tried checking the Disable SSL certificate validation under Tools --> Options. No luck there, either. Also, I do not encounter this problem if I go to a straight to http: it's only happening with https connections.

I've also tried following the exceptionally unclear instructions here:

Someone has to have figured out how to do this, but both Google and Atlassian Answers have come up shy for me, or I'm overlooking the answer.

Any help would be appreciated.

Thank you,

After MUCH struggling, my team finally arrived at the answer:

This answer assumes you are using a stand-alone (non-domain) Windows 7 computer and are trying to use Sourcetree with Stash on a HTTPS address and are receiving the SSL/TLS error.

You need the following:

  • The cert for the server Stash resides on in X.509 or pfx/p12 format. There are numerous websites that will show you how to convert a cert to p12 format. Our experience was that the easiest route was to go from PEM to P12; your milage may vary.
  • The CA cert for the domain the server resides on, also in X.509 or pfx/p12 format.

Copy both certs to the local Windows 7 box.

Double-click on the SERVER cert. Follow the instructions and have the wizard place the cert in the where ever it wants.


Follow the instructions for importing the DOMAIN CA CERT here: ; you want "Adding certificates to the Trusted Root Certification Authorities store for a local computer" (third topic down). Make sure you select your DOMAIN CA CERT when importing.

From there, you should be able to access Stash via Sourcetree. Or at least we were.


This worked for me.

Hello, is there no other way to use a Bitbucket self-signed cert with Sourcetree than to get an 'official' AD domain cert?  We are evaluating both Bitbucket and Sourcetree and it seems a bit excessive to not provide some way to accept the self-signed cert during an eval.


This was driving me nuts, but I finally found a setting to disable cert checks to allow a self signed cert in the SourceTree.exe.config file

        <setting name="SourceTreeHomeWebSite" serializeAs="String">
        <setting name="ReleaseNotesRelativeUrl" serializeAs="String">

************* Set the value to true :)
<setting name="AllowUncertifiedSSLRequests" serializeAs="String"> <value>True</value> </setting>
        <setting name="IsPortable" serializeAs="String">

You may also use the settings menu:
