ATP - receiving 503 Service Unavailable while starting sql developer or Apex
Summarynot able to access sql developer and Apex
ATP Database is up and previously both sql developer and Apex were connecting to it with no problem. currently receiving error "503 Service unavailable" and below message. This is a always-free instance.
The connection pool named: |ocid1.tenancy.oc1..aaaaaaaasaubnllb44x5cdtkrecdb3cpjdtte2oyicivdkt7mt2w74nws6ia-mreport|re| is not correctly configured, due to the following error(s): Exception occurred while getting connection: oracle.ucp.UniversalConnectionPoolException: Cannot get Connection from Datasource: java.sql.SQLRecoverableException: No more data to read from socket"
Any idea what can be the reason for this?
