Lens terminal on Mac Arm

[Francois-Royer]

Describe the bug The terminal in pod or node report "error: unable to upgrade connection: error dialing backend: remote error: tls: unrecognized name" with OSX arm version, intel version work fine.

Our kube api server have been hardenized and support only highly secured TLS Cipher suite. It seems that Lens terminal proxy doesn't support it in arm version: it use TLS ECDH with the following curve secp521r1:secp384r1:prime256v1 on nginx

To Reproduce Steps to reproduce the behavior:

1. Put a proxy in front of kubernetes api with ecdh cipher suite only with curve secp521r1:secp384r1:prime256v1
2. connect to cluster
3. try to open a terminal in pod
4. See error

Expected behavior Arm version work same as Intel version

Environment (please complete the following information):

• Lens Version: 6.2.5
• OS: OSX 13.2.1 Ventura
• dmg

Logs: When you run the application executable from command line you will see some logging output. Please paste them here:

error: unable to upgrade connection: error dialing backend: remote error: tls: unrecognized name

Additional context Intel version work fine on same machine with same configuration so it's pretty sure it's linked to arm version.

@Francois-Royer Are you using the arm64 or amd64 version of Lens Desktop?

[Francois-Royer]

When I use arm64 I have the bug, when I use amd64 it works.

It seems that the issue as also a link with kube config insecure-skip-tls-verify: true. If you add this setting you have the error, if you remove it, it works.
