Connection reset by peer

[pavelpoley]

After i open the app and running some minutes in background i have this error:

` E/REALM_SYNC: Connection[4]: Reading failed: Connection reset by peer
E/REALM_JAVA: Error in __permission:
    CONNECTION_RESET_BY_PEER(realm.basic_system:104): Connection reset by peer
E/REALM_SYNC: Connection[1]: Reading failed: Connection reset by peer
 E/REALM_JAVA: Error in __wildcardpermissions:
    CONNECTION_RESET_BY_PEER(realm.basic_system:104): Connection reset by peer
 E/REALM_SYNC: Connection[2]: Reading failed: Connection reset by peer`

What can be the reason? i am using 2 different configurations, full sync and query based.
The app not crash but data no showing, does it mean i need to sign in again or how to prevent this issue?

Realm version(s): 5.9.1

Realm Sync feature enabled: Yes

Android Studio version:3.3.2 ?

Connection reset by peer is a network error: https://stackoverflow.com/questions/1434451/what-does-connection-reset-by-peer-mean

Most likely you stopped the server or dropped the connection somehow.

[pavelpoley]

I even don't know how to stop the server, it is not randomly happen, it happen every time after 3-4 minutes. I am using cloud platform without additional backend code.

How is your device connected to the Internet? Does it, in general, have problems with connectivity e.g. when using the browser?

[pavelpoley]

I am using WIFI, i don't have problems with Internet, checked without WIFI and on emulator same problem

Does the problem can happen because of open realms/permissionManagers?

[cmelchior]

No, both end of input and connection reset by peer are indications of network problems somewhere.

[cmelchior]

Since these errors are network related errors I'll be closing this issue. If you still think this is an issue with Realm itself we would need a sample project to be able to debug this.

[pavelpoley]

I guess it is somehow related to PermissionManager or system permissions, this connection reset happen after some time when PermissionManager.getPermissions() called.

Also, after this error the non system realms still syncing and updating data but when i try to call PermissionManager.getPermissions() again error is thrown, and i need to restart the app to force PermissionManager work again.

It happen not only on my network, happen at all users that we tested.

I see this error also in Realm todo-full-sync app example, connection reset after about five minutes

If i comment the code with PermissionManager this error not happen.

But lets say it was connection error, it can happen, i think the problem is that after connection is drooped i don't have access to permission manager anymore, it return error. All other realms after drooped connection work fine updating and syncing.
