Description Rik Theys 2020-07-07 14:17:58 UTC 
Description of problem:
Every few days/weeks one of our servers loses network and the journal shows:

Jul 07 13:33:56 gold.esat.kuleuven.be NetworkManager[989]: <error> [1594121636.0006] dhcp4 (ens3): error -111 dispatching events

Jul 07 14:34:08 gold.esat.kuleuven.be NetworkManager[989]: <info>  [1594125248.8290] manager: NetworkManager state is now DISCONNECTING

Our interface has a static IPv6 address and uses DHCP for IPv4. Only the IPv4 address is lost.

It seems the fix from https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/commit/c5d1d4c498c50dfc7d2d18b213a117dd1199f1de is missing?

https://bugzilla.redhat.com/show_bug.cgi?id=1829178 also looks similar.

Version-Release number of selected component (if applicable):
NetworkManager-1.22.8-4.el8.x86_64

How reproducible:

Seems to happen every few days since upgrade to 8.2. Never had this issue with 8.1

Steps to Reproduce:
1.
2.
3.

Actual results:

IPv4 address is removed from interface

Expected results:

IPv4 lease is extended.
