running anyconnect 4.9.0404 with Big Sur. Sometimes when the mac going to sleep and wakes up again, the connection cannot be established. Restart the mac will solve it - or a re-install will also do it. So something needs to be hanging after sleep, but I don´t know what I should look for since the connection cannot be established.
Anyone know about how to solve this ?

Hi ,
There is a bug on AC 4.9 related to Big Sur.
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvv65303/?rfs=iqvred
Could you please perhaps try using latest AC version 4.9.06037 and confirm if the symptoms are the same ?

Hi out there
The problem is certainly not solved - we are seeing exactlyt the same symptoms - we have a base of 100 mac we cannot update to big sur since our "beta-testers" on big sur are suffering under this problem - and that has been on-going now for 1/2 year
we are up on the latest AnyConnect 4.10.02086 as the latest suggestion from Ciscos supporters - but still the same problem

For me, this issue is intermittent but happens a lot and happened on both Catalina and Big Sur. Sometimes it will affect both Ethernet and WIFI or sometime only the WIFI. My colleague and I figured is that if we kill vpnagentd and restart the affected network interfaces, that it will help bring them back without having to restart the Mac. If it helps anyone, here's the bash script that I crafted that serves as a workaround for this so you won't have to reboot:
#!/bin/bash function restartNetworkInterfaces() { net_interfaces=("$@") for net_interface in ${net_interfaces[@]}; do echo "Restarting interface: ${net_interface}" sudo ifconfig ${net_interface} down sudo ifconfig ${net_interface} up ifconfig -u ${net_interface} done } VPNAGENTD="/opt/cisco/anyconnect/bin/vpnagentd -execv_instance" echo "Restarting ${VPNAGENTD}" sudo pkill -9 -f ${VPNAGENTD} ETHERNET_INT=`networksetup -listnetworkserviceorder | sed -En 's|^\(Hardware Port: .*Ethernet.*, Device: (en.)\)$|\1|p'` restartNetworkInterfaces "${ETHERNET_INT[@]}" WIFI_INT=`networksetup -listnetworkserviceorder | sed -En 's/^\(Hardware Port: (Wi-Fi|AirPort), Device: (en.)\)$/\2/p'` restartNetworkInterfaces "${WIFI_INT[@]}"
Another scenario which I felt is related to this is that my MAC will just auto reboot because of a panic from waking up. Did anyone experience this too?

hi again
It looks as if the latest MacOS (11.6.something) and AC 4.10.02086 has solved the problems - been stable since we got these updates

I'm on that version, i.e. 4.10.02086 and I'm still getting the issue.

well - the problem is probably not as much AnyConnect but MacOS - if you are on 11.6.1 then would I guess that the symptoms disappear...

I had this happen today with AnyConnect 4.10.07073 & MacOS Sonoma 14.5 (23F79).
It doesn't happen every time my laptop goes to sleep on the VPN -- usually it's fine -- but today wasn't the first time in recent memory.
