// The SNI option is available for the SIM7080 but I found examples of some other Simcom modules that only need to "enable" SNI". For my module I need to enter a server name, so I input the exact same URL as my cluster's including my ID, is that ok?
AT+SMSSL=1,"isrgrootx1.pem",""
// first quotes are for the root CA - second quotes are for the .crt certificate and it should technically come with a private key, so I leave it empty since I couldn't convert the server certificate as such earlier... is that OK too?

// here I'm always getting +CME ERROR: operation not allowed
Set a Ciphersuite on correct >ctxindex>, in my case is 1:
AT+CSSLCFG=“CIPHERSUITE”,1,0,0x0035
AT+CSSLCFG=“CIPHERSUITE”,1,1,0x002F
Ive added two ciphersuits 0 and 1 on <cipher_index> just in case.
Dissable clock checking on certificate, I dont really know if it is mandatory
AT+CSSLCFG=“IGNORERTCTIME”,1,1
Check certificate, maybe dont needed
AT+CSSLCFG?
Set only root certificate:
AT+SMSSL=2,“isrgrootx1.pem”,“”
Finally connect:
AT+SMCONN
