Download image using SDWebImage, error -999

I am unable to download the image in Objective c Using SDWebImage 4.4.5 version., I tried the following , nothing worked.

Try 1:

[self.thumbnailImageView sd_setImageWithURL:[NSURL URLWithString:thumbnailURLString] completed:^(UIImage * _Nullable image, NSError * _Nullable error, SDImageCacheType cacheType, NSURL * _Nullable imageURL) {

}];

Try 2:

[self.thumbnailImageView sd_setImageWithURL:[NSURL URLWithString:thumbnailURLString] placeholderImage:nil options:SDWebImageRefreshCached completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) { if(image != nil){
            self.thumbnailImageView.image = image;                
        } else {
            NSLog(@"Photo Not Available, fetch");
            [self.thumbnailImageView sd_setImageWithURL:[NSURL URLWithString:thumbnailURLString] placeholderImage:nil options:SDWebImageRefreshCached completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {
                if(image != nil) { NSLog(@"Lo Res Image Loaded by %ld from '%@'", (long)cacheType, imageURL);
                    self.thumbnailImageView.image = image;

                } else {
                    self.thumbnailImageView.image = nil;

                } }];

        } }];

Try 3:

[[SDWebImageDownloader sharedDownloader] downloadImageWithURL:[NSURL URLWithString:thumbnailURLString] options:SDWebImageDownloaderUseNSURLCache progress:nil completed:^(UIImage *image, NSData *data, NSError *error, BOOL finished) {


        }];

Try 4:

SDWebImageManager *manager = [SDWebImageManager sharedManager];

        [manager loadImageWithURL:[NSURL URLWithString:thumbnailURLString] options:SDWebImageDelayPlaceholder progress:^(NSInteger receivedSize, NSInteger expectedSize, NSURL * _Nullable targetURL) {
        } completed:^(UIImage * _Nullable image, NSData * _Nullable data, NSError * _Nullable error, SDImageCacheType cacheType, BOOL finished, NSURL * _Nullable imageURL) {

        }];

Try 5:

SDWebImageDownloader *manager = [SDWebImageManager sharedManager].imageDownloader;
        [manager setValue:@"application/vnd.learning.events.v1+json" forHTTPHeaderField:@"Accept"];
        [manager setValue:@"en-US" forHTTPHeaderField:@"Accept-Language"];
        [manager setValue:@"application/json; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
        //[manager setValue:savedEmail forHTTPHeaderField:@"Email"];
        [manager setValue:savedToken forHTTPHeaderField:@"Authorization"];
        [manager downloadImageWithURL:[NSURL URLWithString:thumbnailURLString] options:SDWebImageDownloaderHighPriority progress:^(NSInteger receivedSize, NSInteger expectedSize, NSURL * _Nullable targetURL) {
        } completed:^(UIImage * _Nullable image, NSData * _Nullable data, NSError * _Nullable error, BOOL finished) {
            self.thumbnailImageView.image = image;
        }];

In all the above cases, getting the following error:

Error Domain=NSURLErrorDomain Code=-999 "cancelled" UserInfo={NSErrorFailingURLStringKey=https://prodServer.azurewebsites.net/api/BAImage?ActionFlagId=97&id=615, NSErrorFailingURLKey=https://prodServer.azurewebsites.net/api/BAImage?ActionFlagId=97&id=615, _NSURLErrorRelatedURLSessionTaskErrorKey=( "LocalDataTask <92586538-B07D-46FB-8694-3B29AA3F0CB4>.<7>" ), _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <92586538-B07D-46FB-8694-3B29AA3F0CB4>.<7>, NSLocalizedDescription=cancelled}

Earlier, we used v3.5.4 version used, able to download the image with the following code. It's working good.

[self.thumbnailImageView setImageWithURL:[NSURL URLWithString:thumbnailURLString]
                            placeholderImage:nil
                                   completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType) {
                                       if (image != nil){
                                           self.thumbnailImageView.image = [self imageResizingToAspetRatio:image];

                                       }
                                   }];

Kindly let me know if did any mistake, or any suggestions.

Update 1: Tried to download the image using post man. Kindly check the image. The same image URL is working on SDWebImage v3.5.4 after i upgraded to SDWebImage v4.4.5, it is not lodging the image.

Is there any configurations am i missing? Installed pod 'SDWebImage/WebP' also, added SD_WEBP=1 in Build settings -> Preprocessor macros.
