"remote error: tls: unrecognized name" when adding git repository

[tgkul]

Hi, I recently setup my Kubernetes cluster and deployed Rancher, Cert Manager and then Argo CD. I have a Next JS web app that I want to deploy to my Kubernetes cluster using Argo CD.

The problem I am facing is with adding git repository in Argo CD. For both public and private repositories on Github and Gitlab, I get following error -

> argocd repo add https://gitlab.com/gitlab-org/gitlab.git --loglevel debug --logformat json

{"level":"warning","msg":"Failed to invoke grpc call. Use flag --grpc-web in grpc calls. To avoid this warning message, use flag --grpc-web.","time":"2024-10-30T18:58:55+05:30"}
{"level":"fatal","msg":"rpc error: code = Unknown desc = error testing repository connectivity: Get \"https://gitlab.com/gitlab-org/gitlab.git/info/refs?service=git-upload-pack\": remote error: tls: unrecognized name","time":"2024-10-30T18:58:55+05:30"}

I can get rid of grpc call error by using --grpc-web flag. It's the second error I am not able to fix.

Here is my setup:

Just out of curiosity I tried running git clone on argocd-server pod but it failed for gnutls_handshake() failed: The server name sent was not recognized. I am not even sure if this is supposed to succeed or fail.

argocd@argocd-server-78c87b9bb6-4v2fc:~$ git clone https://github.com/argoproj/argo-cd.git
Cloning into 'argo-cd'...
fatal: unable to access 'https://github.com/argoproj/argo-cd.git/': gnutls_handshake() failed: The server name sent was not recognized

Can someone help me figure out what I am doing wrong? Let me know if you need more information. I am running out of options.

Hi,
Did you ever find out how to fix this issue? I have the same issue

I solved the problem finally.

I deployed ArgoCD using helm, which allowed me to set repoServer.dnsConfig to

  dnsConfig:
    nameservers:
      - 1.1.1.1
      - 8.8.8.8
      - 8.8.4.4

And 2 lines below set dnsPolicy: "None".

After applying, and restarting the argocd-repo-server container the TLS unrecognized name issue was resolved instantly
