Hi Folks,
In the past month my VPN AnyConnect is constantly reconnecting. From every 3 minutes to every 15 minutes at times. This is a major blocker for attending meetings and workflow interruptions.
I've tried various changes from IPv6 disabling to MTU adjustments but none of these tweaks are correcting the problem.
Macbook Pro 15-inch, 2018
macOS Mojave 10.14.5
Cisco AnyConnect Secure Mobility Client Version 4.7.01076
AT&T Gigabit
Router Model | 5268AC |
Hardware Version | 260-2173300 |
Software Version | 11.1.0.531418-att |
I did do a test and spent 1.5 hours at Starbucks connected to the VPN with no issues. What is it with AT&T and Cisco combination that is causing the constant reconnects?
Thanks for any help.

We're in 2020, and still no fix!? Running macOS 10.15.2 and AnyConnect 4.8.01090 and seeing disconnects anywhere from just over an hour to within a minute of connecting.

This specific problem sealed the deal to move away from AnyConnect.
03-26-2020 06:33 AM - edited 03-26-2020 08:52 AM
Sadly this BS is not exclusive to AnyConnect. I'm having the exact same issues described on a MBPr 16 running 10.15.3 with all three of Fortinet FortiClient, OpenVPN Connect, and Viscosity (commercial OpenVPN client). At first I thought it was a screen saver / sleeping wifi issue, but then noticed more often that I'll drop VPN even while the laptop is being actively used. Apple wifi troubleshooter does not detect the issue as being a disconnect even if left in continuous monitoring mode.
If I capture kernel messages via console, I'm finding very short wifi flaps with messages looking like this:
default 15:53:29.805053-0400 kernel postMessage::1349 APPLE80211_M_BSSID_CHANGED received default 15:53:29.805197-0400 kernel en0::IO80211Interface::postMessage bssid changed default 15:53:29.805330-0400 mDNSResponder <private> default 15:53:29.805255-0400 kernel 001817.167532 wlan0.A[787] updateQoSFastLaneToNetworkState@1137:Enterprise Initiatives: Qos FastLane is Disabled default 15:53:29.805766-0400 kernel com.apple.p2p: IO80211AWDLPeerManager::getInfrastructureState lost infrastructure link default 15:53:29.805773-0400 kernel com.apple.p2p: IO80211AWDLPeerManager::getInfrastructureState infra channel 149 -> 0 default 15:53:29.805778-0400 kernel com.apple.p2p: IO80211AWDLPeerManager::getInfrastructureState(): Infrastructure state changed: BSSID(00:00:00:00:00:00), Channel(0) default 15:53:29.805780-0400 kernel com.apple.p2p: IO80211AWDLPeerManager::interfaceStateChange Infra State Changed, Channel = 0 default 15:53:29.805531-0400 configd en0 link INACTIVE default 15:53:29.805784-0400 kernel com.apple.p2p: interfaceStateChange[2611]: Infra link down, disable dynamic SDB default 15:53:29.805793-0400 kernel com.apple.p2p: IO80211AWDLPeerManager::configureValidAWDLChannels Default alternate 5GHz channel 44 is valid default 15:53:29.805797-0400 kernel com.apple.p2p: IO80211AWDLPeerManager::configureValidAWDLChannels social channel 2G: 6 on 5G: 149 5G Alt: 44 country code: US default 15:53:29.806354-0400 symptomsd SCDynamicStore config_callback: k: State:/Network/Interface/en0/LinkQuality default 15:53:29.806060-0400 configd en0: no SSID
When this happens, it usually recovers within 100-200ms, but because the kernel has sent a 'network change event', the VPN client drops. Now I have other non-Mac (and Mac non-T2) systems on the same access points, same SSID, same vlan, that are not experiencing this issue.
I'm going to test out the bluetooth and/or airdrop disabling to see if it produces any positive change; I'd at least like to be able to definitively blame apple by disabling features to see the problem go away.
Edit: ugh. No change. Airdrop disabled, bluetooth disabled, and I got a whole 20 minutes out of my VPN before it booted me.
08-18-2020 06:00 AM
Has anyone found a resolution to this issue? I have disabled bluetooth and airdrop and continue to see the connection drop. I am on AnyConnect 4.8.03036 and macOS Catalina 10.15.6. The problem started occurring recently on my machine after the latest installation of the Catalina update.

You bet, called up Cisco IT twice in last 2 weeks and it ended with the issue being with Mac. Seems like nobody wants to solve this problem. So much for productivity and wfh
