The first thing I would do is get a second NIC and configure
active-passive bonding. network issues are too common to ignore in HA
setups. Ideally, I would span the links across separate stacked switches.
As for debugging the issue, I can only recommend to look closely at the
system and switch logs for clues.

I have the issue on two of my nodes. Each node has 1ea 10gb connection. No
bonding, single link. What else can I look at? I manage the network too. I
don¹t see any link down notifications, don¹t see any errors on the ports.

I turned corosync output to debug. How can I go about troubleshooting if
it really is a network issue or something else?
Jun 09 13:06:59 corosync [QUORUM] Members[4]: 1 2 3 4
Jun 11 14:10:17 corosync [TOTEM ] A processor failed, forming new
configuration.
Jun 11 14:10:29 corosync [QUORUM] Members[3]: 1 2 3
Jun 11 14:10:29 corosync [TOTEM ] A processor joined or left the
membership and a new membership was formed.
Jun 11 14:10:29 corosync [CPG ] chosen downlist: sender r(0)
ip(10.70.100.101) ; members(old:4 left:1)
This is, to me, *strongly* indicative of a network issue. It's not
likely switch-wide as only one member was lost, but I would certainly
put my money on a network problem somewhere, some how.
Do you use bonding?
