Should I change that setting on the head node and compute nodes, or just the head node only?.When I change it on all nodes (testing with only two computers for now), Progress hangs on Determing memory availability on distributed machines on Local Machine.nAnd I need to abort the process.nnWhen I change it on only the head node, I get an execution error in message manager:n   [error] Could not start the memory inquiry solver:check distributed installations, MPI availability, MPI authentication and firewall settings. (8:16:24 AM Mar 26, 2021)n   [error] Simulation completed with execution error on server:Local Machine. (8:16:44 AM Mar 26, 2021)nnI have made no changes to the firewall since I last successfully distributed a solve with the old license settings shown the earlier screenshot.
