SMTP Email Error and Publishing Confusion

When building a simple SMTP mail activity using our relay server, something strange is happening between two published versions of the SAME process.

When my coworker publishes the process, we run the job and the SMTP mail fires and completes correctly.

When I publish a CLONE of the project from my computer, we get the following error:

“No compatible authentication mechanisms found.”

We’re essentially out of troubleshooting options at this point. Has anyone else experienced or does someone have an idea of where this error is starting?

Is there an issue with something on my computer that is carried over when publishing to Orchestrator?

Figured it out:

Our UiPath.Mail.Activities packages were different versions (i.e. mine was out of date).

Updated my Mail.Activities to latest version and it worked without any other changes.
