Why I can't upload large files?

In tFLOW there are 2 main reasons that explain why a large file cannot be uploaded:
 
  • the first one is regarding the components and the architecture of tFLow that does not allow to upload a file larger than 1.9 GB.
    This is the maximum file size accepted by tFLOW
     
  • the second reason could be because you are using 3rd part web tool like DDoS protection, HAProxy or similar that could limit the maximum file size.
    For example CloudFlare is limiting to 100MB, 250MB or 500MB (depending on the selected plan) the upload size:

    This means that when using CloudFlare any file with a size larger than what allowed by the plan, is rejected by CloudFlare, not by tFLOW.
