Hello guys !!!

i'm a beginner in kamailio technology and i want to use kamailio http_client module to get  data from API, but
i got :

Access error : Unauthorized
Access Denied Wrong Password


My user IDs are correct. API's encryption is MD5 (digest Auth ). 
So i use:

modparam("http_client", "authmethod", 2)
...

modparam("http_client", "cipher_suites", "ecdhe_ecdsa_aes_128_gcm_sha_256, rsa_aes_128_gcm_sha_256"
then 
modparam("http_client", "cipher_suites", "rc4-md5")

Can someone help me please ?
