Unexpected EOF while Lens up is starting the Cluster

Question

I have a Kubernetes (RKE) test environment that I'm working on ,and up until last week my Lens app worked fine.

My lab is running on Ubuntu 20.04. 3 nodes. 1 NFS server which is also my Ansilbe server. All these is running on Vmware workstation.

Today when i open the Lens, i see this error:

when i connect to my Cluster, after a couple of seconds, i see the error:

E0322 08:42:41.679547 5801 proxy_server.go:147] Error while proxying request: unexpected EOF

E0322 08:42:41.701049 5801 proxy_server.go:147] Error while proxying request: unexpected EOF

malformed HTTP response

And this is my Kubeconfig file:

Even when i want to configure a new Cluster in Lens, and upload the configuration file, after a few seconds, i get the error i pasted above.

I'll appreciate your help on this. (already opened a new bug in github for lens App).

I also attached a screenshot from the Lens logs while it's trying to load the cluster.

Best regards, Nahum.

Hopefully, the screenshots I've added will help.

This is the Proxy Address in my cluster environment, as you can see, i have resolving to the PROXY.
