Before changing the account ( following the blog) you have to make sure couple of things.
- New service account should have Database Permission SPdataAccess role on the Content Database and Config database. You have to manually set this on the database Server.
- Also make Sure new service account is part of IIS_IUSRS group on the server.It is local group...go to computer management > Local User and Groups.
- Reset IIS after changing the App Pool account ( after following Blog steps).
If stil throwing the error, check the event log on the server to get more error information.

1User needs to be in the local IIS WPG group to run an app pool. Check the event viewer. May 1, 2017 at 0:49
Please follow
Have the application pool identities for all farm web applications configured with Logon as batch and Impersonate a client at authentication local rights. After granting the identities these rights, restart the application pools.
