Mongodb – I cannot connect to mongo db atlas using spring boot

I have a spring microservice application linked with mongodb atlas database, yesterday my project works fine but today I’m getting this error

here is my application.properties file

spring.data.mongodb.uri=mongodb+srv://denver:*****@product-service.wt2swod.mongodb.net/?retryWrites=true&w=majority
spring.data.mongodb.database=product-service

eureka.client.fetch-registry=true
eureka.client.service-url.defaultZone=http://localhost:8761/eureka

spring.application.name=product-service
server.port=0

I tried to add those properties but never worked

@SpringBootApplication(exclude = {
  MongoAutoConfiguration.class, 
  MongoDataAutoConfiguration.class
})

    I would recommend you to – -> set socketKeepAlive to true (which is by default true in the latest versions of the native driver) -> set maxConnectionIdleTime < net.ipv4.tcp_keepalive_time in this way your JVM would reap the connection and not the other way around.

    I had the same issue when I was connecting to the Atlas cluster through my local machine. I had to whitelist my IP address through the Atlas dashboard again.

    Whitelist your current IP address in your mongo DB cluster

    Check "Whitelist your current IP address in your mongo DB cluster" in this article for more information. https://baraksaidoff.medium.com/fixing-mongoserverselectionerror-while-connecting-mongodb-with-node-js-213aaf0bf596
