I am facing the same issue , whenever uploading the document we encounter 413 error , uploading directly to server there is no issue.

    No, ASM is not configured , we are using LTM only.

    When we configured SSL Pass through in LTM it works but when SSL Bridging is used then issue arises,

    Some issue with SSL connection establishment between LTM and the server.

    413 Error is not send by F5 rather by server when SSL negotiation fails between the two.
