We started with a two node RAC database setup, at v19.11.0.0 (19c base install + April 2021 patch set) on AIX 7.2.  After we applied the 19c July 2021 Combo GI+OJVM patch set we have a maintenance network that we use to connect to the databases and we cannot connect to databases anymore, we were able to before applying the July 2021 patch set.  The application servers utilize SCAN and can connect just fine.

Howdy, Stranger!
