Unable to access specific rest apis due to azure error

My application using spring rest and deployed in Azure server. Created rest apis using spring rest.

Am able to access all rest urls, except in one scenario.

for eg: http://mydomain123.com/api/abc , http://mydomain123.com/api/xyz/abc

Am able to access above urls

http://mydomain123.com/api/bin , http://mydomain123.com/api/xyz/bin , http://mydomain123.com/api/bin/dfdff

But above urls having bin word with which am getting below error:

The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

I am trying as below,but not working at all:

<configuration>
<system.webServer>
    <rewrite>
      <rules>
        <rule name="Main Rule" stopProcessing="true">
                <match url=".*" />
                
            </rule>
        </rules>
    </rewrite>
</system.webServer>
</configuration>

Please someone help me out to fix above issue (I should be able to access rest apis even having word "bin" in it)
