What happened?

argocd-provider pod is failing to connect to argocd

time="2024-04-03T18:12:28Z" level=fatal msg="Failed to establish connection to argocd-server.argocd.svc:443: read tcp 100.64.78.83:49608->172.20.75.34:443: read: connection reset by peer"

How can we reproduce it?

A test curl in another pod is able to get to argocd api:

curl -X GET argocd-server.argocd.svc:443/api/version -H "Authorization: Bearer $ARGOCD_TOKEN"
{"Version":"v2.10.5+335875d","BuildDate":"2024-03-28T15:02:45Z","GitCommit":"335875d13e018bed6e03873f4742582582964745","GitTreeState":"clean","GoVersion":"go1.21.3","Compiler":"gc","Platform":"linux/amd64","KustomizeVersion":"v5.2.1 2023-10-19T20:13:51Z","HelmVersion":"v3.14.3+gf03cc04","KubectlVersion":"v0.26.11","JsonnetVersion":"v0.20.0"}

Provider config:

  runtimeConfigRef:

What environment did it happen in?

Crossplane version: 1.15.1 Crossplane Provider argocd version: 0.6.0 EKS: 1.24 ArgoCD: v2.10.5+335875d

That looks like a network misconfiguration to me. Have you checked that the you can connect to ArgoCD from the same pod as the provider?

This fix here was to set plainText to true
