Hi @jimbo881 Thank you for being an active member of our community. Did you check if there is already an instance of MySQL running? Usually this kind of errors appear when you try to start a process that is already running, and has the port allocated. Check this: `netstat -anpe | grep ":4567" | grep "LISTEN"` The results for me (I started a nc session to listen on that port… this are not the results you will see) ```auto [jplasanz@pc103orchestratorapp-01 ~]$ sudo netstat -anpe | grep ":4567" | grep "LISTEN" tcp 0 0 0.0.0.0:4567 0.0.0.0:* LISTEN 705643 290161493 10163/nc tcp6 0 0 :::4567 :::* LISTEN 705643 290161492 10163/nc ``` The last column reports the process identified and the executable program that is running and has the port allocated. Thank you. Pep ---

The problem is on the donor node: 2022-11-01T15:33:12.049288Z 57 [Note] Access denied for user ‘sstuser’@‘localhost’ (using password: YES) 2022-11-01T15:33:12.052292Z 58 [Note] Access denied for user ‘sstuser’@‘localhost’ (using password: YES) I cannot get it to take the sstuser password no matter what I try… This is v5.7 and the wsrep\_sst\_auth=sstuser: is set in the /etc/my.cnf file correctly… ---

This first error indicates you are running multiple PXC instances on the same host - > [@jimbo881](#): > > 2022-11-01T11:30:00.721346Z 0 [Warning] WSREP: error while trying to listen ‘ssl://0.0.0.0:4567?socket.non\_blocking=1’, asio error ‘bind: Address already in use’ > 2022-11-01T11:30:00.721385Z 0 [ERROR] WSREP: failed to open gcomm backend connection: 98: error while trying to listen ‘ssl://0.0.0.0:4567?socket.non\_blocking=1’, asio error ‘bind: Address already in use’: 98 (Address already in use) > at gcomm/src/asio\_tcp.cpp:listen():928 This is a new error - can you verify that the sst user can log in with the password from the my.cnf config? > [@jimbo881](#): > > 2022-11-01T15:33:12.049288Z 57 [Note] Access denied for user ‘sstuser’@‘localhost’ (using password: YES) ---

The first error is from the down node 3. The reason for it is the second error from the donor node 2 which is the access denied error. I verified I can log in with the password from the my.cnf file on the joiner node on the donor node… ---

Hi @jimbo881 Can you share the full error logs again? I don’t see the link here between “port already in use” error and “access denied for sstuser” error ---

It came down to: set global wsrep\_sst\_auth=“sstuser:newpass”; Being set correctly on the donor node. Thanks for all the responses.
