I upgraded to NPM 12.2 last week, and ever since I can no longer add new nodes. It's getting hung up on the "Choose resources" step and just sits there spinning indefinitely without ever listing any resources so I can complete the add (I've waited over an hour on one just to be sure). The SNMP test verifies successful on the to-be-added node just fine (as it always has), but something has changed with the upgrade and I can't figure out what. I did have to upgrade SQL server from 2008R2 (I chose to go to 2016) before NPM would let me upgrade, so not sure if that's a factor. I'm stuck.. have tried three different nodes and none of them list resources when trying to add them.
