Parsing error in cattle-cluster-agents

Hello Rancher-Community!

So I’ve got a single node of Rancher 2.3 working but when adding a local cluster, the cattle-agent remain in CrashLoopBackOff status and their logs are like this:

INFO: Environment: CATTLE_ADDRESS=10.0.2.15 CATTLE_AGENT_CONNECT=true CATTLE_CA_CHECKSUM=2b7a76b2a6c4a54a936e9ccd21b0c594f563f61d1e7d8bbbbcdf6a83e550987b CATTLE_CLUSTER=false CATTLE_INTERNAL_ADDRESS= CATTLE_K8S_MANAGED=true CATTLE_NODE_NAME=kube-worker-1 CATTLE_SERVER=https://rancher.xxxxxxxx.xxx
INFO: Using resolv.conf: nameserver 10.0.2.2
INFO: https://rancher.thinkpad.tld/ping is accessible
INFO: rancher.xxxxxxx.xxx resolves to 196.178.xx.xx
parse error: Invalid numeric literal at line 1, column 7

Any idea what it is trying to parse at this stage?
