Database connection not found on windows server

My project has 5 different connections. No matter what I do on one of them (conn_firstout) it says it doesn’t exist. I’ve deleted it, recreated it…it is clearly there. The database is there. All the others with the same credentials work perfectly. It works in development. I’m on windows server w apache xamp. Fortunately it’s not a critical app and I can probably rewrite it, but just bizarre. Thoughts?
