Another common error you may see when working with a Microsoft Windows based virtual private network is VPN error 619 - "A connection to the remote computer
could not be established." (With some older VPN servers, the error message says "The port was disconnected.") Like VPN error 800, error 619 can happen either when trying to establish a new connection to a VPN server or when suddenly disconnected. If you encounter it, check the following:
→ More - Common VPN Error Codes Explained
- If two or more VPN clients are installed on the computer, ensure only one is running to avoid conflicts. Check both for running applications and also for Windows services.
- Firewalls and antivirus programs may be running that block access to the VPN ports. Temporarily disable these to troubleshoot.
- Try other standard repairs and troubleshooting steps - reboot the client computer, delete and re-install the VPN client configuration settings, and find others who have working setups to compare for network configuration differences

Thanks…
Problem is resolved.
Sometimes a home router can be the source of the problem. It may not handle PPTP or L2TP with address translation.
As Pål says above, the actual connection may prevent VPN tunnels.
If you’re trying to VPN away from where you normally do (hotel wifi) try a different connection if possible.
Switching to our 3g dongles worked around an issue at an industry event for us.
Thanks guys I had the Stateful firewall ON on the Cisco VPn hence it was throwing error 619 once i disable stateful firewall the issue resolved itself.
Certain VPN software (and routers that support hosted VPN services) don’t support passwords longer than 10 digits.
I was getting error 619 until I shortened my password.
can agree with Omoronovo – just had this problem on a draytek router.
thnx.
my problem is resolved….
I agree with pal,
I resolved this issue by enabling PPTP Pass Through setting in Modem..

I checked all of them but still have a problem and can’t get connected,what should i do now?
For cisco routers with an inbound acces-list add the following:
permit gre host 10.1.1.1 any
Where 10.1.1.1 is the remote VPN end point.
Hi there,
I have two computers apparently with the same configuration, in the same LAN and trying to establish a vpn connection to the same remote address. One works perfeclty well and the other shows a 619 error. Both have Windows FW activated and both have the same AV SW and config (McAffee).
Does anybody knows how to “log” the vpn con process (as in Cisco VPN client) in a separate Windows? Is there any Win Command that does that?
Thanks!
Unable to connect after Virgin engineer made some router changes.
After reading the above I went in to Advanced Settings and set “PPTP Pass-Through = Allow” in the Firewall. Now everything is working fine again. Thanks!
I uninstalled the Symantec Endpoint Protection (antivirus) software provided by my university and that seems to have resolved the issue. So, it seems the firewall and/or antivirus programs are the main source of this error.
Thanks mate … you were really helpfull
I had Avast! Firewall and Malwarebytes Antimalware running, turned both off and it worked.
I was so worried when I saw this error on my very new laptop.. But as soon as I disabled the security software , I am on internet…
Thanks – my problem is resolved.
I have a weird situation where I am able to connect to one VPN that uses SSTP protocol without any issue at all, but if I try to use the other VPN (not at the same time obviously) using IKEv2 it errors out with a return code of either 619 or 809. At first I thought perhaps we were blocking some form of VPN on the network (which is what error 809 infers), but I have completely taken down the firewall and allowed all protocols through the gateway, yet I still get the same messages over and over again. All necessary updates have been installed and the anti-virus software has been disabled.
It’s making me insane, Any ideas?
in security settings of the vpn connection in windows, allow unsecure connection worked for me
