Sourcetree with embeded mercurial and TLS 1.0 deprecation.
Asked by MathieuRoy:

Hello, since december 1 2018, bitbucket cloud have deprecated TLS 1.0 and 1.1  
See <https://bitbucket.org/blog/deprecating-tlsv1-tlsv1-1-2018-12-01>  

I am using bitbucket cloud using mercurial embeded version 4.6.2 and i am unable to commit anymore. Upgrading Sourcetree or the embeded mercurial version doesn't seems to work. Here is my error log. I hope it help.  

<br />

hg commit -y --logfile C:\\Users\\\[User\]\\AppData\\Local\\Temp\\ztbppcxc.3gx  

hg push --new-branch default
