TFS Plugin - Unable to get local issue certificate exception when creating release notes

TFS Version: 2018 update 3
Build Agent Version: 2.147.1
Octopus Version: 2018.9.17


I’m getting the following exception with the error code “UNABLE_TO_GET_ISSUER_CERT_LOCALLY” using the TFS/Azure DevOps extension when running the “Create Octopus Release” task. The release still gets created, but the release notes do not contain the associated work item notes because of the TLS error.

We have an Octopus server on-prem with a company self-signed cert. The TFS build agent is also configured to use schannel for git.

Hi Ken,

Thanks for getting in touch. I did some digging and it looks like there may be a way we could disable the SSL errors in the calls back to TFS, but this really doesn’t feel like a great idea.

This is a bit out of my area of expertise, but I suspect the root cause of the issue is that the build agent isn’t configured to trust the issuer of the certificate being used by TFS. Could you try installing the certificate on the agent and/or configuring it to trust the certificate authority from the self signed certificate?
