PPP stuck in REQUEST_SENT when CONFIG_GSM_MUX is enabled #47995

Hy everybody, I am working with Thales PLS83-W modem and use the CONFIG_MODEM_GSM_PPP=y to get PPP interface up and running and everything works fine, after the modem is registered to the network I get an IP address and PPP interface is up and running. But when I enable the CONFIG_GSM_MUX=y I run into problems. After the modem is registered to the network I don't get the IP address anymore, and PPP is stuck in the REQUEST_sent phase and never gets UP.
I had to increase the GSM_CMD_AT_TIMEOUT from 2 to 5 seconds, and tried swapping the PPP and AT channels:
CONFIG_GSM_MUX_DLCI_PPP=1
CONFIG_GSM_MUX_DLCI_AT=2
but nothing helped

These are the logs when CONFIG_GSM_MUX=y is disabled and everything works fine:
