Hi

I have a strange problem with a customer's installation.
I can not access custom registers through Rest API.

I can access standard registers, so I know everything is set up correctly.
I can access custom blocks.
I just can't access custom registers - I get an empty reply if I specify a valid register, and an error if I specify an invalid one.


To make things stranger, I can access the custom registers if I set the whole thing up on OS X

This is on 8.5 2018-12-07


Has anyone experienced this, or has any idea how to resolve it?

Thanks

David
