Good day,
Today, my Cisco AnyConnect Client suddenly stopped working and started giving the following error messages:
1st dialog: VPN Service is not available.
2nd dialog (after pressing mandatory OK): The VPN Agent service is not responding. Please restart this application after a minute.
I have searched the internet for possible fixes and have tried the following things:
- Uninstalling and re-installing the software. (As administrator and whatnot)
- Connecting with AnyConnect network adapter on and off.
- Disable Internet Connection Sharing (ICS) service.
- Trial and error turning off other services to see if they somehow conflict.
- Turn on services that were also turned on on another laptop that does have a working client to see if somehow certain required services got disabled.
- Allow service to interact with desktop (In the "Log On" tab of the vpnagent service)
- Manually starting vpnagent service.
- Uninstalling, deleting any leftover Cisco directories, deleting Cisco registry entries, restarting, and then install again.
- Deactivating windows firewall, windows defender, and Avira antivirus.
Some odd things I have noticed:
- When changing the account to "Log On" in the vpnagent service to LOCAL_SERVICE or NETWORK_SERVICE, I can at least start the service and it will allow me to enter credentials to the vpn I want to connect to. However, it will always instantly give an error when the right credentials are entered. (Tried using wrong credentials and it rightfully tells me that they're wrong)
- When manually trying to start vpnagent service with "Log On" account LOCAL_SYSTEM it immediately stops after starting. Sometimes the service gets stuck in a loop, infinitely trying to start and stop at rapid succession. At this moment, my laptop ventilator is blowing like mad so I restart.
- When manually trying to start vpnagent service sometimes the following error message is given:
Windows could not start the Cisco AnyConnect Secure Mobility Agent service on Local Computer.
Error 1067: The process terminated unexpectedly.
- On the other two setups mentioned below, the network adapter for AnyConnect are actually turned off when the VPN connection is working. Is it supposed to be off?
Some other things I have tried that worked, but not for my own Windows installation:
- Installing the same client on Ubuntu OS on the same laptop (works like a charm)
- Installing the same client on another laptop running the same Windows 7 version (works like a charm)
I am totally out of ideas. Any suggestions are greatly appreciated!
