Disable SSL validation 

Is there any way to disable ssl validation? 

PS: I work with local testrail instance behind the firewall  

```bash
Caused by: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
```
