I solved by updating manually mongoose version to 6.2.2
<pre><code> WARN @nestjs/mongoose@9.0.2 requires a peer of mongoose@^6.0.2 but none is installed. You must install peer dependencies yourself.
</code></pre>
I realize due to this error on npm install
just use:
<pre><code> npm install mongoose@6.2.2 --save
</code></pre>

For those people who cannot solve this problem by the answer above, according to the new specs of <code>nestjs/mongoose</code>.
It might be solved by deleting the line: <code>useNewUrlParser: true</code>.
For me, it works in both ways.

Worked for me when I've added &quot;directConnection=true&quot; to the connection string.
&quot;If set to true, the driver will only connect to the host provided in the URI and will not discover other hosts in the cluster. Direct connections are not valid if multiple hosts are specified.&quot;
Before:
<pre class="lang-js prettyprint-override"><code>MongooseModule.forRoot(

</code></pre>
After:
<pre class="lang-js prettyprint-override"><code>MongooseModule.forRoot(

My application was working fine in <code>&quot;@nestjs/mongoose&quot;: &quot;^8.0.0&quot;</code> and I faced this error when I changed to <code>&quot;@nestjs/mongoose&quot;: &quot;^9.0.0&quot;</code>.

I'm trying to connect with remote database.
I've solved this problem with this adding this 2 query parameter
<code>?authSource=admin&amp;directConnection=true</code>
Full URI
<code>mongodb://username:password@host:port/dbname?authSource=admin&amp;directConnection=true</code>
And if you get this error
<code>MongoParseError: Password contains unescaped characters</code>
wrap your password with <code>encodeURIComponent</code> function.
<code>mongodb://username:${encodeURIComponent(password)}@host:port/dbname?authSource=admin&amp;directConnection=true</code>

Are you using Node 17 or above? Node now prefers IPv6 over IPv4 from Node 17 so <code>localhost</code> will translate to <code>::1:</code> and not <code>127.0.0.1</code> - <a href="https://github.com/nodejs/node/issues/40537" rel="nofollow noreferrer">related issue</a>. Your local MongoDB server is probably running on <code>127.0.0.1</code> and thus your application is unable to connect. Try connecting to <code>mongodb://127.0.0.1:27017/snaptoon</code> as <a href="https://stackoverflow.com/a/73537289/5863472">this answer</a> suggested.

I'm trying to connect to the database, seems like the set-up is correct, but for some reason, it says that it is not available.
<code>app.module.ts</code>
<pre><code>import { Module } from &quot;@nestjs/common&quot;
import { MongooseModule } from &quot;@nestjs/mongoose&quot;;
import { ConfigModule } from &quot;../config&quot;;
import { CreatorModule } from &quot;./creator.module&quot;;

@Module({
 imports: [
 MongooseModule.forRoot('mongodb://localhost:27017/snaptoon', {
 useCreateIndex: true,
 useUnifiedTopology: true,
 useNewUrlParser: true,
 }),
 CreatorModule,
 ],
 controllers: [],
 providers: []
})

export class AppModule {}
</code></pre>
The error is: <code>ERROR [MongooseModule] Unable to connect to the database. Retrying (9)...</code>
I'm using <code>'@nestjs/mongoose': '9.0.2'</code>
