PPP LCP Negotiation stops at state 4.

[jeff160490]

I am facing problem with PPP protocol. LCP cannot negotiate configuration.
I'm using Renesas S7G2 development board with Netx Duo version 6.21 and Quectel EC21-E modem.
My IDE is E2Studio
I tried diagnose problem by analyzing PPP logs as well as analyzing PPP packets in Device Monitoring Studio.
I think it may be related to OptionType=2 on LCP negotiation (ACCM) but I am not sure. I've seen that this option it's not implemented in Netx Duo. S7G2 Board send ACK packet in respond to LCP ConfRequest, but as I sad earlier, I am not sure if it analyze ACCM option.

I expected to have complete negotiation and look what happen later. But without it I can't connect to Azure IOT

Logs and console output

ppp_log.txt

I don't have any problems with LCP negotiation under Linux I have tested it with PPPD without any problem.
I would be really glad if someone can help with it.
