DH (Fixed Diffie-Hellman Ephemeral)
Security
Static Diffie-Hellman[429][430] is a variant of Diffie-Hellman[99][100][101][102][103] key exchange[133] protocol that has no forward secrecy[127][128][129][130], 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.
Recommendations
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[405][406][407][408] version.
Encryption algorithm SEED[384][385][386] is a block cipher[78][79][80][81] which is considered secure[387], but leading client applications do not use this algorithm. Unless your application or requirements specifically call for their use, it is generally safer to avoid cipher suites that are not adopted and supported by a critical mass of the industry.
Recommendations
Remove the cipher suite from the list of cipher suites supported by your server.
Remove the cipher suite from the list of cipher suites supported by your server or at least set the cipher suite order explicitly and any cipher suite modes be preferred over ciphers suites with CBC modes.

Encryption Key Size

128
Security
The symmetric key[185][186][187] withkey size[184] more than 128 bits as it is should be according to National Institute of Standards and Technology[470][471] so it is not vulnerable to preimage attack[67] 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[61].
Recommendations
Remove the cipher suite from the list of cipher suites supported by your server.
