Hi, @MKirby Thanks for testing it and reaching out. the product has a Troubleshooting guide here:
As well as a FAQ besides, please review and we're always open to feedback on them to help future users get stated faster.
for your case, do you mind sharing what version you are using? And I'd like to know if you are using the stand-alone Agent or attempting to enroll it in Fleet?
If you are not using the 7.13 release, please do check the guides / info for the prior releases as the architecture (and start up) has changed significantly between 7.12 to 7.13.
If Agent didn't start with the -f paramater, you can omit it. it saves you one prompt in the command line, and if it fails again you may get a more detailed error message. Please do post screenshots or text copy of what you're seeing!
I can offer up, too, that if you are using stand-alone mode the Docs should help elaborate the configuration a lot, and which ports to use to cite creds and get the Agent's sub-processes access to post to ES. This is just a guess as you reference copying over specific single files, which is not recommended if you are NOT using stand-alone mode.
Happy to try to help more, cheers.
