Agent Lost Contact - Unable to connect - SSL handshake error or connection reset

[Obiageli Adegbite]

My Window 2019 Agent Keeps loosing contact, due to SSL Handshake errors, when I delete/rename the agent.jks file  it goes to idle and after 10 -15 minutes returns to lost contact what can i do?

kindly help

Hello

This seems like an old GoCD version that you are running - are you able to report what version your server and agents are?

It might be a bit difficult to provide great suggestions for these older versions, since the in-built TLS support for GoCD was replaced in GoCD 20.2.0 and the communications mechanism between server and agent was changed in GoCD 21.1.0 meaning it's a bit tough to recall all the details here.

I have a few questions though:

• Did something change in your setup (agent or servers) after which this started happening?
• Are all agents having problems or only a subset of agents?
• What do the server logs say at the same time as the agent has these errors?
  

I am completely guessing, since I am not familiar with GoCD's old TLS/mTLS setup, but this might mean certificates have expired somewhere and your agent has somehow lost trust in the server (or vice versa - the server no longer trusts the agent). To know why that is would require a bit more digging though.

-Chad

Replying here since I am unable to see the original mail in my mailbox:

If you have renamed the agent.jks file and are able to re-establish contact (you've said the agent is idle for 10-15 minutes), then please try the following:

1. Disable the agent and then enable it again.

2. If removing it and adding it back is an option, then please do so

3. Uninstall the agent and then reinstall it.

I have had to do (2) and (3) above when the agent bootstrapper was so far outdated from the server that just the built-in agent auto-update was not enough.

Separately, did you update your Java installation? That once led me to have to delete the agent.jks like you have had to.

Hi Chad,

Yes I was using an older version 18.11, I'll install a newer and see if it corrects the error

[Obiageli Adegbite]

Hi Sriram,

 I have tried your 3 suggested steps and it is still loosing contact I will uninstall and try install a different version and see how that goes

[Obiageli Adegbite]

I am still getting the same error with the installed higher version

[Chad Wilson]

Hi Obiageli

GoCD v19.8.0 still has the same core TLS setup as earlier versions to my knowledge. The more significant changes in defaults were made in 20.2.0 onwards. However an upgrade won't necessarily resolve your issue (as it would potentially require different work to support TLS/HTTPS) - I was just explaining why it might be a bit more difficult to get help with such issues; since this part of the design has changed significantly in the last few years.

In any case, the root error does look a bit different now: javax.net.ssl.SSLException: readHandshakeRecord Earlier it was javax.net.ssl.SSLHandshakeException: Received fatal alert: certificate_unknown

This does imply a basic TLS handshake problem with your server, which could be caused by a number of things, but possibly relates to an issue of compatibility between the certificate presented by "go.dev.scitorque.com:8154" and your agent's configuration or Java version.

I'm afraid to help more without guessing/speculating I'd need answers to the original questions I asked about your setup - and perhaps a couple of other ones that might help at the bottom

• Did something change in your setup (agent or servers) after which this started happening?
• Are all agents having problems or only a subset of agents?
• What do the server logs say at the same time as the agent has these errors?

• Which Java version is your agent bootstrapper running with?
• How is the agent being installed (via MSI installer? or running standalone using system-installed Java version?)

-Chad
