Oracle 19c runInstaller reports PRVF-5311 while checking SSH connectivity I am trying to install Oracle 19c RAC on three nodes, running RHEL 8.3. GRID installation was ok. But, Oracle DB SW install using runInstaller(GUI) is stuck with this issue while checking for SSH connectivity between nodes.
Error Reported:
Cause - Either passwordless SSH connectivity is not setup between specified node(s) or they are not reachable. Refer to the logs for more details.  Action - Refer to the logs for more details or contact Oracle Support Services.  More Details

When I tried runcluvfy, it reports ok.

There is nothing in Oracle support site.
Try below solution:
Rename the original scp. ( find where is the scp executable file present)
mv /usr/bin/scp /usr/bin/scp.orig
Create a new file .
vi /usr/bin/scp
Add the below line to the new created file .
/usr/bin/scp.orig -T $*
Change the file permission.
chmod 555 /usr/bin/scp
Once installation is done , you can revert to the original
mv /usr/bin/scp.orig /usr/bin/scp
