Jenkins wasn't used in a while, now trying again, and it can't connect to the cluster. 

Jenkins pod will not create slaves:
-> going to the cloud config
-> testing the connection will report "A problem occurred while processing the request"

- Cluster hasn't had changes in a while, either
- team mentions deprecation of JDK
- this log shows near top of Jenkins logs:

> 2024-10-01T12:14:03.561544631+13:00 error: You must be logged in to the server (Unauthorized)

- team reports no other changes
- 20 other Jenkins instances running in this cluster, only affects this namespace: `nzdd-jenkins-pipeline`

- start of the Java traceback:

Error injecting constructor, java.lang.NoSuchMethodError: 'void org.yaml.snakeyaml.parser.ParserImpl.<init>(org.yaml.snakeyaml.reader.StreamReader, org.yaml.snakeyaml.LoaderOptions)'
  at io.fabric8.jenkins.openshiftsync.GlobalPluginConfiguration.<init>(GlobalPluginConfiguration.java:109)

OpenShift version 4.14    

    1.
    2.
    3.
    

    Jenkins has an established connection like all the 20 other Jenkins instances. Newer deployment works fine, this is troubles with older deployments. 

    Jenkins able to communicate with OCP cluster. 

    From the pods, both these fields are false, but that should not be the reason for Jenkins not being able to communicate.
