[BUG] exporter doesn't start listen on 9161 port when ORA-01033 is present

[kirxcore]

Description

Using 2.2.0 version with go-ora driver. We have some DBs, and when some of them are on maintenance and there is ORA-01033 error, exporter stops listen on 9161 port, URL (localhost:9161) is not active (no messages in logs like level=INFO source=tls_config.go:347 msg="Listening on" address=[::]:9161). Logs are good, no any go-errors, only ORA-01033. When I comment sections with DBs that are on maintenance and restart exporter, exporter starts working (i see in logs message level=INFO source=tls_config.go:347 msg="Listening on" address=[::]:9161)

Expected Behavior

When there are DBs that are offline/on maintenance or smth, exporter doesn't stop and scrapes metrics from other available DBs.

Environment

• Docker Swarm
• Exporter version: 2.2.0-go-ora

Can you confirm if this error is exclusive to running the exporter with the go-ora driver?

It's both go-ora and standart driver when I have an issue
