F5 LTM upload a file issue

Hi Adolfo,

there are a couple of ways to troubleshoot this issue:

1. Try with a different browser ( I guess you did that already).
2. Open the developer tools of your preferred browser (F12 or from the menu) - look for messages that could explain this behaviour.
3. Try a tcpdump on the BIG-IP, look if you can identify an issue there.

If you are new to packet capturing, I will recommend you the following resources

• K411: Overview of packet tracing with the tcpdump utility
• K2289: Using advanced tcpdump filters
• K1893: Packet trace analysis
• In case your application is using TLS: K31793632: Create a Decrypted Capture Without Using an iRule
• and in general: Chris Greer's YouTube channel
