Keep getting java.io.InterruptedIOException: timeout in Retrofit2

I get java.io.InterruptedIOException: timeout rarely in my office.

However, it keeps occurring in stores.

So, I set

client.addInterceptor(httpLoggingInterceptor)            .connectTimeout(5, TimeUnit.SECONDS)            .callTimeout(5, TimeUnit.SECONDS)            .readTimeout(5, TimeUnit.SECONDS)            .writeTimeout(5, TimeUnit.SECONDS)            .retryOnConnectionFailure(true)

But, this didn't work.

So, What I did in .enqueue()

fun startPay(){    // ... Service Generator and so on...    override fun onFailure(call: Call<ResultData>, t: Throwable) {        when(t){            is InterruptedIOException ->{                Thread.sleep(1000)                startPay()            }            else->{                Toast.makeText(this, t.toString(), Toast.LENGTH_SHORT).show()            }        }    }}

I am guessing this occurs because more than two clicks in short time or I am calling 3 consecutively after 200 response. ex. A call -> 200 response -> B call -> 200 response -> C call -> 200 response -> UI Update.Now, it catches the exception and retry the api call. I think this has no reason to be interrupted by the same thread or other thread..

This solution is fine in general. But the problem is when I pay something It must call just once.

this InterrupedIOException: timeout(Not SocketTimeout) seems cancel the connection before getting the response from server, the server is sending the response well and has no problem.

Some questions in stackoverflow mentioned Crashlystics. I am using it but I shouldn't remove it.

I am using:

    // Firebase    // Import the BoM for the Firebase platform    implementation platform('com.google.firebase:firebase-bom:26.0.0')    implementation 'com.google.firebase:firebase-core'    implementation 'com.google.firebase:firebase-auth'    implementation 'com.google.firebase:firebase-auth-ktx'    implementation 'com.google.firebase:firebase-config' // remote config    implementation 'com.google.firebase:firebase-analytics'    implementation 'com.google.firebase:firebase-analytics-ktx'    implementation 'com.google.firebase:firebase-crashlytics'    implementation 'com.google.firebase:firebase-perf'    implementation 'com.google.firebase:firebase-config-ktx'    // Network    // okhttp: https://github.com/square/okhttp    implementation 'com.squareup.okhttp3:okhttp:4.7.2'    implementation 'com.squareup.okhttp3:logging-interceptor:4.7.2'    implementation 'com.squareup.retrofit2:adapter-rxjava2:2.9.0'    implementation "com.squareup.retrofit2:converter-gson:2.9.0"    implementation 'org.conscrypt:conscrypt-android:2.2.1' // optional

The error is here:
