Can not install Helm Tiller on worker node

I am using locally deployed k3s cluster on my locally deployed Gitlab server.
Whenever I try to Install Helm Tiller, it gives the following error:

Something went wrong while installing Helm Tiller

* Operation failed. Check pod logs for install-helm for more details.

when I check the logs of the pod install-helm ,

This error occurs only when k3s tries to install helm on worker node. If it is installed on master node, helm tiller is installed without any issue.
Things I have tried:

I have added rules in ip tables
Modified resolve.conf (commented out the search entry(s))

Any help would be appreciated. Thanks
