SHCONN AT Command fails on SIMCOM 7080G

My SIMCOM is a 7080G with las Firmware updated to: APRev:1951B16SIM7080,B16V01 QCN:SIM7080G_P1.03_20201226 IMEI:860016041830931

I follow exactly the HTTP procedure described in: SIM7070_SIM7080_SIM7090 Series_HTTP(S)_Application Note_V1.02

Everything is correct for the setup, IP is correct, carrier and PDP connection is fine. When the system issued AT+SHCONN it always gives ERROR.

Tested with different SIMs With different caller RxTx software. One is C++ of myself, trivial, Second is ATCommandTester utility

I will attach a log.

Thanks in advance, And kind regards, Horacio

Have you tried disconnecting any previous http(s) instance with 'AT+SHDISC' before setting up the new instance?
