eth_subscribe newHeads not returning data

[fadeev]

Trying new heads again, and it's returning the subscription, but not data.

From BlockPi:

It is a bug from the new node client. Our test shows that v20.0.2 returns data but v20.0.5 does not.

Is this related to #3050 ?

Odd, it's working now.

[skosito]

that makes sense since #3050 is the only issue that was changing something regarding websockets, and that is not part of v20, it will be for v21
