File uploading issue in High Load IIS website on Windows Server - expert required

Job ID: 38954860

Budget: $10 – $30 USD

currently we are facing file upload timeout issue on high load iis website
My IIS server is running a PHP 7 web application. The server has high performance and reasonable upload speed (over 200-300 MB/s), but it still takes forever to upload a file.

Submitting forms, database queries and other operations run in a short time frame, however, uploading a file doesn't work and simply times out after a while.

The server previously ran perfectly, however, the issue has started happening for the past 7-8 days when load increases

I need an expert in IIS/Windows server configuration to troubleshoot the uploading process and resolve the issue.

You should be able to work using Any Desk/Team Viewer or any other remote desktop solution.
