I am facing the same issue. Traffic is reaching the Virtual Server (VS) with a pool attached to the actual backend server. The application is working fine, but when trying to upload a 4MB file, I receive the error:


"Request Entity Too Large – The requested resource does not allow request data with POST requests, or the amount of data provided in the request exceeds the capacity limit."

Troubleshooting steps attempted:

  1. Disabled renegotiation in the server SSL profile.
  2. Disabled renegotiation in both client and server SSL profiles.
  3. Attached HTTP profiles (LAN Optimized, WAN Optimized).
  4. Applied HTTP Compression, Web Acceleration, and HTTP/2 profiles.
  5. Changed protocol to TCP and UDP.

Captured a TCP dump, and no RST packets were found, but I observed an "Encrypted Alert."

Any suggestions for further troubleshooting?
