I've had similar issues using kubectl to access some tools that made a lot of requests (polling, which is something argocd does I believe).

Setting this environment variable helped a lot: KUBECTL_PORT_FORWARD_WEBSOCKETS=true

Note: because Google's quality is falling you won't be able to find this variable using their search, but you can read about it by searching Bing or asking an LLM.
