Key Exchange Method
static Diffie–Hellman Ephemeral (DH)
Static Diffie-Hellman is a variant of Diffie-Hellman key exchange protocol that has no forward secrecy, and does not protect past sessions against future compromises. If long-term secret keys or passwords are compromised, encrypted communications and sessions recorded in the past can be retrieved and decrypted.
Remove the cipher suite from the list of cipher suites supported by your server or replace the cipher suite with it's Ephemeral Diffie-Hellman version.
The symmetric key withkey size more than 128 bits as it is should be according to National Institute of Standards and Technology so it is not vulnerable to preimage attack and it cannreliably prove that message came from the stated sender (its authenticity) and has not been changed, so connection is not open for a man-in-the-middle attack.
