Hi @nirrobi,

 

Based on research, I think this issue is more related to oracle. You can take a look at below blog if it solve your issue.

ORA-12571: TNS:packet writer failure – One of the hardest problems I’ve had to resolve

 

In addition, you can ask your oracle dba(database administrator)to trace this issue and try to solve it.
