Analysis

CodeArts Repo supports TLS1.2 and TLS1.3.

Solution

Run the following command on the Git Bash client to check your Git version:
```
git --version
```
If your Git is earlier than 2.6.0, upgrade it to the latest version. The latest Git supports TLSv1.2 by default. If your Git version is 2.6.0 or later, specify the TLS protocol version:
```
openssl s_client -connect test.com:443 -tls1_2
```

**Table 1** Known incompatible clients
Client	Description
Git Credential Manager for Windows< v1.14.0	TLSv1.2 is not supported. Upgrade the Git client to the latest version. Select to install the Git Credential Manager during the upgrade.
Git on Red Hat 5	TLSv1.2 is not supported. Upgrade to a later version.
Git on Red Hat 6	Upgrade to 6.8 or a later version.
Git on Red Hat 7	Upgrade to 7.2 or a later version.
JDK7	TLSv1.0 is used in JDK 7 by default. Any client, such as Eclipse JGit, running on an earlier version of JDK is affected. This can be resolved by enabling TLSv1.2 in JDK 7.
JDK6 or earlier	TLSv1.2 is not supported. Upgrade to a later version.
Visual Studio	Visual Studio comes with specific versions of Git for Windows and Git Credential Manager for Windows (GCM). Microsoft has updated the latest version of Visual Studio 2017 to work with the TLSv1.2 Git server. We recommend that Visual Studio users upgrade to the latest version by clicking the in-product notification flag or checking for updates directly from the IDE. Microsoft has provided additional guidance on the Visual Studio developer community support forum.

Third-party Git GUIs

If you use a third-party Git client, such as Eclipse, JetBrains, SourceTree, VSCode, Tower, or TortoiseGit, you are advised to download the latest Git Bash and use the native Git instead of the built-in type in the tool.
