keys here need to be

GoogleKeys__ClientId
GoogleKeys__ClientSecret

GoogleKeys__ClientId
GoogleKeys__ClientSecret

also prefer using dotnet user-secrets for secrets for development, and keep appsettings.json committed to your repository that way

for some reason after i deploy, i can see my app now but when i am on the homepage it redirects me to the error page saying: Request ID: Name does not resolve.

Ares•4mo ago

i think the reason for the name error is the fact that it says An error occurred using the connection to database 'realtime_poll' on server 'tcp://db:5432'. though not sure why its failing to connect in prod but works fine locally. Host=db;Port=5432;Database=realtime_poll;User Id=<id>;Password=<password>; this is the connection string i am using in dev and prod

Ares•4mo ago

also when i try to login now, it says the redirect uri is wrong. but i cant add http uri to google cloud console, it wont let me. so im not sure why its givin gme https instead of http. I cant login anymore, even though my docker runs just fine

i'm not familiar with render, dunno. but that sounds like you dont have the db container running in same docker network so it can't resolve the address or at all
