ORA error in 15.5 install - oracle db panel

Hello,

We are running into an error when we are on step 14 - theOracle Database Panel in the 15.5 Syamtec upgrade.

We are upgrading from 15.0 and have run through all the readiness tools and upgraded our DB to 12c.

We confirmed that the password is correct and verified the username. The service name is protect as usual and we have that fully qualified as we see in the tnsname.ora file. We have tried the user name as fuly qualified, not, capital, not any combo you can think of - we still get the below error.

Error Calling OCISessionBegin: ORA 01017: invalid username/password; login denied

thank you!
