Issue with uploading file on a web browser while running test on an Azure pipeline

[abhay2506Singh]

I am executing some tests where i am expected to upload pdf/excel files (Single/multiple). I am using the file from project repository itself and it works perfectly on local execution.
But when executing the same test on Azure pipeline(test run on a linux machine), the test does not give any error, but the file also does not get uploaded. Please help.

Element :
<input _ngcontent-ehr-c4="" multiple="" style="display: none;" type="file">
Code variations tried:

1. Multi File

const filepathval = path.join(__dirname, "../../../PDF_Files_Folder");
var filePath:string[] = METHOD_TO_Get_FILE_ARRAY_FROM_FOLDER_PATH(filepathval);
var newFileName[] = METHOD_TO_GET_FILENAMES_CONCATENATED_WITH_TIMESTAMP(filePath);
for (let index = 0; index < filePath.length; index++) {
            files.push({buffer:FS.readFileSync(filepathval [index]),name:newFileName[index],mimeType: 'application/octet-stream'});
        }
await this.page.locator(this.selectors.fileInputElement).setInputFiles(files);

2. Single FIle

const excelFilesForUploadPath = path.join(process.cwd(), '../../../PDF_File_NAME.pdf');
await this.page.locator(this.selectors.fileInputElement).setInputFiles(filepathval);

3. Even tried using API

static async uploadFileService(request:APIRequestContext,filePath:string[], newFileName:string[], fileType:FileType) {
    const form = new FormData();
    for (let index = 0; index < filePath.length; index++) {
      const fileBuffer = FS.readFileSync(filePath[index]);
      form.append('file', new File([fileBuffer],newFileName[index],{ type: 'application/octet-stream' }));
    }
    
    const headers:any = await HeaderDataClient.getHeadersUploadFile();
    var baseURL = process.env.ENV_VAR_VAR==='qa'?
      "BASE_URL_QA":
      "BASE_URL_UAT";
    const response = await request.post(baseURL + resource, {
      headers: headers,
      multipart: form
    });
    return response;
  }

In all cases, files upload locally, but when executing the same code on Azure pipeline (runs on linux machine) , the loader for file upload keeps rotating, but the file does not load and the test times out.
For case 1 and 2, i.e. UI uploads, No errors appear in log.
For case 3, ie API , i ma getting 'apiRequestContext.post: connect ETIMEDOUT'
