Tell us what’s happening:
I don’t know what is wrong with my code. I asked someone to look at it, and they said nothing is wrong with my code, especially the part to connect to MongoDB Atlas. I have tried all kinds of methods to solve it but none of them work. This is my error: Failed to connect to MongoDB Error: querySrv ENOTFOUND _mongodb._tcp.cluster0.mongodb.net
at QueryReqWrap.onresolve [as oncomplete] (node:internal/dns/promises:293:17) {
errno: undefined,
code: ‘ENOTFOUND’,
