Hi,

You can connect to F5 system (Linux)using root and run curl or wget. From tmsh you can jump to bash using:

tmsh run util bash

If it is working with version 13 and it is the same send and receive string, maybe is due to TLS protocol used for F5 monitor. Note: TLS1.2 monitor support was added in 11.5.0. You can check cipher configuration running the next command in F5:

openssl ciphers -v ''

Cipher string is 'cipherlist' monitor setting.
