Key Exchange Method

Diffie–Hellman Ephemeral (DHE)
Security
Ephemeral Diffie-Hellman[142][143][144][145] is a variant of Diffie-Hellman[269][270][271][272][273] key exchange[467] protocol that has forward secrecy[135][136][137][138], and does protect past sessions against future compromises. If long-term secret keys or passwords are compromised, encrypted communications and sessions recorded in the past cannot be retrieved and decrypted.
Recommendations
Always prefer cipher suites with PFS property over the non-PFS ones. Note that performance considerations implies preferring Ephemeral Elliptic-curve Diffie–Hellman[91][92] over Ephemeral Diffie-Hellman[142][143][144][145].
Encryption algorithm Triple DES[216][217][218] is a block cipher[524][525][526][527] which is still recognized as secure, but deprecated. It has multiple vulnerabilities[396][397][398][399] (eg: sweet32 attack[496][497][498][499], meet-in-the-middle attack[37], brute-force attack[555]) and it is considered as weak and disallowed by National Institute of Standards and Technology[428][429] after 2023.
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[193][194][195] withkey size[438] more than 128 bits as it is should be according to National Institute of Standards and Technology[428][429] so it is not vulnerable to preimage attack[215] 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[414].
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 setup yout server to enforce changing session key regularly (rekeying[567]).
