mongoose: Connection fail on any Mongoose version over 10.7.12 [Ubuntu 20.04]

Hello. I’m working on a Ubuntu 20.04 machine.

{ useNewUrlParser: true, useUnifiedTopology: true, useCreateIndex: true, useFindAndModify: false, }

These are my connection options.

"mongodb+srv://[CENSOR]:[CENSOR]@maineatcluser.rsb2q.gcp.mongodb.net/destinations?retryWrites=true&w=majority"

and this is my connection URI.

Details of libraries and versions I get Error on :-

"mongodb": "^3.6.2",
"mongoose": "^5.10.11",

Node Version : 14.15.0

Details of Working setup :-

"mongodb": "^3.6.2",
"mongoose": "5.7.12",

Node Version : 14.15.0

I am pretty sure the mongodb version in my package.json probably doesn’t matter but including anyways.

**Please Note that I have 0.0.0.0 whitelisted so this is not an IP Whitelist issue.

Also the problem only persists on this Ubuntu 20.04 Machine. I have a Windows 10 Setup in home [Development environment] Where it’s all okay.**
