Node Red Read timeout problem

Hi, 

I've been experiencing and issue with the Data Layer Subscribe node.

Whenever I try to recieve data via this node I get it twice, but on the third attempt , I recieve the message "Read timeout, received no data in undefinedms, assuming connection is dead". This pattern continues... So I recieve data twice and then the message again. Se picture below:

I'm using Node-Red 1.20.2 and 1.20.13

Does anybody knows this kind of error message / problem?

Thanks in advance.
