I have n8n running in one docker container and 23cfree db in another. Connection to DB from host (VScode) works, but in n8n node im getting an error:
ORA-28041: authentication protocol internal error
2025-09-19 18:35:57 Help: https://docs.oracle.com/error-help/db/ora-28041/
I tried with reseting password to strong one (no success).
I tried also adding lines in sqlnet.ora (no success)
SQLNET.ALLOWED_LOGON_VERSION_SERVER=12
SQLNET.ALLOWED_LOGON_VERSION_CLIENT=12
What is the error message (if any)?
