RestKit 404 error on ios

The following method calls the Rest API (http://128.199.186.47:8080/DenkoStationServer-1/denkoservice/price).

- (void)displayInternetConnectivityMessage {
    NetworkStatus netStatus = [self.internetReachability currentReachabilityStatus];

    if (netStatus == NotReachable)      {
        if ([self isMyanmar])
            [self.view makeToast:@"tifwmeuf zGifhrxm;yg"];
        else
            [self.view makeToast:@"No internet connection"];        
    } else {
        NSURL *baseURL = [NSURL URLWithString:@"http://128.199.186.47:8080/DenkoStationServer-1/denkoservice"];
        NSURLRequest *request = [NSURLRequest requestWithURL:baseURL];

        RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[Price class]];
        [mapping addAttributeMappingsFromDictionary:@{@"id": @"ron95", @"ron95": @"ron92", @"dieselNormal": @"dieselNormal", @"dieselSpecial": @"dieselSpecial", @"postDate": @"postDate"}];

        RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:mapping method:RKRequestMethodGET pathPattern:nil keyPath:@"price" statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

        RKObjectRequestOperation *objectRequestOperation = [[RKObjectRequestOperation alloc] initWithRequest:request responseDescriptors:@[ responseDescriptor ]];
        [objectRequestOperation setCompletionBlockWithSuccess:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
            if ([self isMyanmar])
                [self.view makeToast:@"qmAmESifh csdwfqufjcif; atmifjrifonf"];
            else
                [self.view makeToast:@"Server connection successful"];
            [self updateLocalPrice];
        } failure:^(RKObjectRequestOperation *operation, NSError *error) {
            NSLog(@"error: %@", [error localizedDescription]);
            if ([self isMyanmar])
                [self.view makeToast:@"qmAmESifh qufoG,fr&yg"];
            else
                [self.view makeToast:@"Connection with server failed"];
        }];

        [objectRequestOperation start];
    }
}

This call should return JSON like this:

[{"id":1,"ron95":700.0,"ron92":700.0,"dieselNormal":700.0,"dieselSpecial":700.0,"postDate":1435465383000},
{"id":2,"ron95":800.0,"ron92":730.0,"dieselNormal":700.0,"dieselSpecial":730.0,"postDate":1435819788000}]

Instead of receiving the JSON, the call is returned the following error:

It looks like a server error but the service can be called from other devices. Have I made any mistake in the code that calls the service?

Status 404 is most definitely not a server error. You should really go just to Wikipedia, for example, and read up what all the http status codes mean, or you will be lost forever.

For starters, it is not an error. It is a status. It doesn't say something went wrong, it informs you what happened. 404 means: Resource not found. You asked for a resource, the server fully understood what you are looking for, and it found that whatever you are looking for just isn't there. If the data was there, it would have found it, but it wasn't there. There's not a hint of a server error.

Now obviously you might have made a mistake, and you are not looking for what you wanted to look for. That's your fault.

Change 

NSURL *baseURL = [NSURL URLWithString:@"http://128.199.186.47:8080/DenkoStationServer-1/denkoservice"];

to

NSURL *baseURL = [NSURL URLWithString:@"http://128.199.186.47:8080/DenkoStationServer-1/denkoservice/price"];

and 

RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:mapping method:RKRequestMethodGET pathPattern:nil keyPath:@"price" statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

to

RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:mapping method:RKRequestMethodGET pathPattern:nil keyPath:nil statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
