Connection refused when running rasactl start

[Deprecated] Rasa X Community Edition
1

Dear Rasa family, I am still using Rasa X for one of my projects. Unfortunately recently I had to restart the server with the RASA X installation. Now I get the following error when running rasactl start:

Error: Get "https://127.0.0.1:33073/api/v1/nodes?labelSelector=node-role.kubernetes.io%!F(MISSING)control-plane%!D(MISSING)": dial tcp 127.0.0.1:33073: connect: connection refused

This is my values.yml file

rasax:
  tag: "1.1.1"
eventService:
  tag: "1.1.1"
dbMigrationService:
  tag: "1.1.1"
rasa:
   versions:
     rasaProduction:

     rasaWorker:

   additionalChannelCredentials:
     socketio:
       user_message_evt: user_uttered
       bot_message_evt: bot_uttered
       session_persistence: true
   tag: "3.1.0-full"
   rasaPlus:
     enabled: false
debugMode: false

Does anyone have an idea on how I can resolve this issue?

Thank you in advance,

Sören
