Unable to telnet through internal load balancer

We have requirement where we are asked to create private link. This inturn requires internal load balancer which we created on top of VM.
Now when through bastion I telnet the required ssh and custom port I am able to do that.

azureuser@vm-bastion:~$ telnet 10.1.0.4 8007
Trying 10.1.0.4...
Connected to 10.1.0.4.
Escape character is '^]'.

But the moment I try to do that through internal load balancer IP. It fails

azureuser@vm-bastion:~$ telnet 10.1.0.5 8007
Trying 10.1.0.5...
Connected to 10.1.0.5.
Escape character is '^]'.
Connection closed by foreign host.

Please can you help fix this?

I have used a Standard Load balancer as per the requirement of a Private link. If this isn't working how can we get the response with private end point?

@AmitVengsarkar-1175 , This is expected behavior as SNAT is not supported on internal Azure load balancer.

Also, there is similar ask here in this feedback section where you can provide your feedback and upvote the same for its future availability.
