Hi Bhavin
You do not have the relevant authentication certificates (cacert, clientcert, clientkey) configured. You can upload the relevant certificates and try again. Related commands are as follows:

AT+QSSLCFG=“cacert”,< SSL_ctxID> [,

< cacertpath > ]

AT+QSSLCFG=“clientcert”,< SSL_ctxI

D> [,<clientcertpath>]

AT+QSSLCFG=“clientkey”,< SSL_ctxID

> [,<clientkeypath>]

If you don’t have a certificate, try AT+QSSLCFG= “seclevel”,2,0 ignore authentication.

@tabor.tang-Q ,

Hi ,
i removed AT+QSSLCFG=“seclevel”,2,2 and tried to connect using SAS token.
It worked fine.
Thank you.
