Just as a followup,
The current go-agent I have installed is version 22.1.0-13913:
[root@mbv01 ~]# yum list --installed | grep gocd
go-agent.noarch 22.1.0-13913
@gocd
While the server is running version v21.3.0.
gocd_manager.1.djkifkhv5351@mbs01 | jvm 1 | [Wed Apr 06 16:47:28 CEST
2022] GoCD Version: 21.3.0-13067
gocd_manager.1.djkifkhv5351@mbs01 | jvm 1 | [Wed Apr 06 16:47:28 CEST
2022] Java Version: 15.0.2
Could the version difference between the client and the server be the cause
of this?
Best Regards
Rasmus
