SimpleMembership works locally but can't find SqlServier Instance when published - authentication

Question

So I'm using SimpleMembership and locally it runs fine. The SQL Server it's using (locally) is actually the remote server, so I know the connection string is correct. However, when I publish the website and try to hit a protected endpoint, it hangs for a bit and then returns an error. I've tried changing my connection string in my web config to (local) as my web host recommends (the db is on the same box, I guess), but no luck. I did delete the defaultConnection entry from the web.config since I didn't use it, so I was wondering if that would have broken something else that I'm unaware of.

Answer 1

I figured it out right as I posted this lol. I decided to post the answer, hopefully it helps someone else.
Basically, I failed to fix database connection name with the user context in the acccount model
public class UsersContext : DbContext
{
public UsersContext()
: base("defaultConnection") // I forgot to change this to my new connection string
{
}
public DbSet<UserProfile> UserProfiles { get; set; }
}
