Key Exchange Method
Name
SRP (Secure Remote Password)
Security
The Transport Layer Security Secure Remote Password[580] cipher suite[189][190]s provide secure communication by establishing key exchange[133] based on one or more party's knowledge of a password, using a Secure Remote Password[177][178][179] which is an augmented Password-authenticated key agreement[156][157] protocol. Some cipher suites verify authenticity[75][76][77] of the parties only by SRP while others use it together with public-key cryptography[164][165][166]. The algorithm is considered secure [180][181], 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
If your application or requirements specifically call for the use of algorithms which are not used by the leading client applications set the cipher suite order explicitly and cipher suites used by the leading client applications be preferred over the ones which do not used by them.

Encryption Type
Name
3DES EDE
Security
Encryption algorithm Triple DES[295][296][297] is a block cipher[78][79][80][81] which is still recognized as secure, but deprecated. It has multiple vulnerabilities[298][299][300][301] (eg: sweet32 attack[22][23][24][25], meet-in-the-middle attack[62], brute-force attack[54]) and it is considered as weak and disallowed by National Institute of Standards and Technology[470][471] 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.
A+
Encryption Key Size
Name
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.
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[174]).
