Description of problem:
Occured every time when I tried connect to my work VPN server
SELinux is preventing NetworkManager from 'unlink' accesses on the file timestamps.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that NetworkManager should be allowed unlink access on the timestamps file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'NetworkManager' --raw | audit2allow -M my-NetworkManager
# semodule -X 300 -i my-NetworkManager.pp
