I assume that you don't set a player's admin level to 5 when you login into RCON.

pawn Код:

CMD:setlevel(playerid,params[])
{
    if(PlayerInfo[playerid][Level] < 4 || !IsPlayerAdmin(playerid)) return SendClientMessage(playerid, 0xF69521AA,"You can't use this command!");//Doesn't let admins under level 4 set an admin level
    new id, level;//Creating the id variable to store the selected id and a level variable for the chosen admin level.
    if(sscanf(params,"ui",id,level)) return SendClientMessage(playerid,0xF69521AA,"USAGE: /setlevel [id] [level(1-4)]");//Check if the player inputted a username or id and a admin level.
    if(!IsPlayerConnected(id)) return SendClientMessage(playerid,0xF69521AA,"The specified player is currently not connected!");//Checking if the selected user is connected or not.
    if (!(0 <= level <= 4)) return SendClientMessage(playerid,0xF69521AA,"Please specify an admin level between 0 and 4");
    new file[64],PlayerName[24];//Creating a variable to store the file path, and a variable to store the players name.
    GetPlayerName(id,PlayerName,sizeof PlayerName);//Retrieving the selected id's name,
    format(file,sizeof file,"Admin/%s.ini",PlayerName);
    PlayerInfo[id][Level] = level;
    SendClientMessage(playerid,0xF69521AA,"You have successfully changed the selected user's admin level");
    SendClientMessage(id,0xF69521AA,"Your admin level has successfully been changed, congratulations!");
    return 1;
}

OR instead, simply do -

pawn Код:

stock GetPlayerFromIP( ip[] )
{
    new pIP[16];
    for(new i = 0; i < MAX_PLAYERS; i++)
    {
          GetPlayerIp(playerid, pIP, 16);
          if( !strcmp( pIP, ip ) ) return i;
          else continue;
    }
    return -1;
}

public OnRconLoginAttempt(ip[], password[], success) 
{ 
    if(success) 
    { 
         if( GetPlayerFromIP( ip ) != -1 ) return ( PlayerInfo[playerid][Level] = 4 );
    }
    return 1;
}
