GoCD server/agent missing communication

[Darly Senecal-Baptiste]

Hi, 

I wanted to install 2 GoCD agents in the same box as GoCD server ; and then, run those agents and server as Linux services. Once the server and the agents are started up for the first time, the server registers them  but both of the agent name is the same; and there is no other configuration to manually update those names but at the config.xml file.

Once those agent names are updated at the config.xml file, the server log provides the following errors

...
2015-07-01 13:30:28,972  WARN [744277562@qtp-70968940-12] log:76 - javax.net.ssl.SSLException: Received fatal alert: internal_error

...

Once the server and agents get restarted, the server present these messages

 In addition, one of the agents (let's say agent1) log provide the following error

This log from the agent and server got me thinking that there something cut off between server and agent1. Agent2 gets its own cookie from the server.

How can I make server and agent to connect properly right after renaming the agent names? Thanks

[Darly Senecal-Baptiste]

The only action for now is to keep the agents names as is. Because it seems there is not other way around to rename it.

With version 15.3 you can change the agent name while auto-registering and via the API

Thanks for the information Ketan :)

I assume you meant 15.2? I thought this feature was coming in that release.
