Getting MongoServerSelectionError: Server selection timed out after 30000ms from localhost:5173

Question

Hi All

I have a mongodb database wrapped inside Azure CosmosDB, I am using a node.js v16.17.1 application using the backend as azure CosmosDB. This application is deployed as a ContainerApp in Azure, there it is working fine while connecting to cosmos-db.

When I connect through localhost:5173:
It was working fine, but suddenly i am getting the below error from a particular day.

MongoServerSelectionError: Server selection timed out after 30000 ms
    at Timeout._onTimeout (node_modules/mongodb/lib/sdam/topology.js:291:38)
    at listOnTimeout (node:internal/timers:559:17)
    at processTimers (node:internal/timers:502:7) {
  reason: TopologyDescription {
    type: 'ReplicaSetNoPrimary',
    servers: Map(1) {
      'my-db.mongo.cosmos.azure.com:10255' => ServerDescription {
        address: my-db.mongo.cosmos.azure.com:10255',
        type: 'Unknown',
        hosts: [],
        passives: [],
        arbiters: [],
        tags: {},
        minWireVersion: 0,
        maxWireVersion: 0,
        roundTripTime: -1,
        lastUpdateTime: 7381815,
        lastWriteDate: 0,
        error: null,
        topologyVersion: null,
        setName: null,
        setVersion: null,
        electionId: null,
        logicalSessionTimeoutMinutes: null,
        primary: null,
        me: null,
        '$clusterTime': null
      }
    },

There are no permissions or network issue as I have allowed public network access to the db instance and it was always working.

even from mongsh <connectionstring> i am getting the same error.

Connection : is through my home wifi network which uses wpa2 personal. Before sometime back i was using wpa security. I am using a mac . My organization disallowed wpa security so i switched to wpa2 and ever since i notice this error when connecting from my localhost with my wifi network

ConnectionString:
mongodb://my-db-:abcdefghijklmnopqrst==@my-db.mongo.cosmos.azure.com:10255/?ssl=true&replicaSet=globaldb&retrywrites=false&maxIdleTimeMS=120000&appName=@my-db@

Mobile hotspot:
Able to connect with my mobile-hotspot in the same machine to the same remote db without any errors. both with the mongosh as well as nodejs app

Any inputs here? Thanks
