Session pooler returns: “FATAL: Tenant or user not found”

[k62634316-web]

Tried multiple CLIs:
psql -h aws-1-ap-northeast-2.pooler.supabase.com -p 5432 -d postgres
-U postgres.lzysiwmglvwbgosabii sslmode=require

All return the same error:
FATAL: Tenant or user not found

I confirmed:

1. Network access OK (Direct connection works)
2. IPv6/IPv4 routing OK
3. Database password reset / verified
4. Role postgres and pgbouncer have rolcanlogin=true

Conclusion:
This looks like a Session Pooler tenant → role mapping issue inside Supabase infrastructure.

Requesting “Pooler mapping re-sync” or “Credential Refresh” for this project.

Nothing will happen from a discussion thread here to your project, if it is your project.
Triple check your instance id. Not sure if the one you are showing is masked but usually I think they are 20 characters, your is 19.
Your error is about that part being wrong.
