I am getting below error while configuring Orcale thin account
below screenshot has error and tnsnames.ora file. I have set up the Orcale db on my personal device. Please suggest how to fix the error

Hi @Siva_Venna,

localhost will not work because it refers to a Snaplex node that you are using, not your machine. You need to provide IP address or another hostname. Please make sure that your database instance is accessible from the Snaplex (VPN, Firewall etc).
