Problem:

I am trying to setup a mariadb galera cluster with 3+ nodes
in Alma Linux 9.4 env. The mariadb version is 10.11.6-1 and 
galera version is 26.4.16 and socat version is 1.7.4.1-5.

The first node is started with new_cluster option
and the database is up and running. When I try to add the second node
to the cluster it is always failing with following error.

WSREP_SST: [ERROR] Possible timeout in receiving first data from donor in gtid stage: exit codes: 124 0 (20240708 20:03:10.560)

I am not sure where the problem is. The wsrep_debug setting did not help much.

The configuration, most of the donor and joiner log snippets are included.

Appreciate if some one could comment where the probelm could be or what could be done to get some more failure logs or isolate the problem.
