[libmbim][ModemManager]cannot connect to proxy: Could not connect: Permission denied
In fedora os, When the pc is started, the mbim cannot be initialized after wwan is identified, but the mbimcli command is used to query the MBIM.
The mbimcli -p -d /dev/wwanmbim0 --no-close --query-raido-state command is used
BASE INFO: MM: 1.20.6-3.fc39
Test steps:
- Install the module and start the pc
- Check whether the module can be identified normally and the information is correct.
Expected results:
The ModemManager detects the module and the information displayed is normal
Actual results:
When the ModemManager detects the module, the information queried by “mmcli -m a” does not contain the mbim interface, and other basic information about the module (such as the version number) cannot be obtained.
