ChEMBLdb Connector (input) problem

Hello every,

I recently use the node “ChEMBLdb Connector input”, which works without any problem. However, there is a error like:

WARN ChEMBLdb Connector Input 0:242 The XML URL may be invalid: PKIX path building failed: unable to find valid certification path to requested target.

This resulted in a empty data table.

I am sure the input is correct.

Is there someone meet this problem as well?

Thanks in advance.
