# Error when pulling source code from azure devops

## post by paul.ferrand on May 25, 2023

Hello,

I successfully configured my Source control (it’s an azure devops 2020 on-premise) in Nexus Lifecycle, but when I take a look at the logs I have the following error:

```

I can’t figure out what’s wrong, can you help me ?
I deployed Nexus Lifecycle on kubernetes (docker container) and my Azure Devops is deployed on a Windows Server 2016.

Thanks for your help.

Hi [@paul.ferrand](https://community.sonatype.com/u/paul.ferrand)! I think this will also best be addressed by our Support team which [you can do here](https://support.sonatype.com/).
