Re: Windows 11 Pulse Secure Constant Reconnecting and Disconnect

I do not understand your solution / cannot find the screens to edit.

Can you post a few printscreens to help me out?

Re: Windows 11 Pulse Secure Constant Reconnecting and Disconnect

@NicolasRouquette Thanks for sharing the event logs. So, it looks like we are matching "Known Issue # 3 : Pulse Desktop Client continuously changes between connected and connecting states when it is connected to PCS that is configured in SSL Transport mode."

 

Reference - https://kb.pulsesecure.net/articles/Pulse_Secure_Article/KB44885/?kA13Z000000L3Zj

 

But the question to ask, Why Windows 11 transitions to SSL mode when there's ESP configured on the server side? Meaning, do we see any ESP packets leaving out from the physical interface of the Windows 11 machine? please take a wireshark capture on the physical interface and confirm.

 

I guess, you have both Windows 11 and 10 connected over the same network, is that correct?  If yes, then I suspect, something on the endpoint side is blocking the UDP 4500 traffic when clearly another client from the same network works perfectly fine with the same VPN server.

[email protected] I believe you're enquring about the post that has been marked as solution.

For that, please type ncpa.cpl in your windows search, network adapter will get listed, find "Pulse Secure" adapter which will be visible only after connecting to VPN, then right click > properties > enable JNPRNS.

To be honest, that shouldn't have made any difference WRT stability of connection. It's ok to disable JNPRNS as it'll not cause negative impact.

 

For Windows 11 known issues - please refer to https://kb.pulsesecure.net/articles/Pulse_Secure_Article/KB44885/?kA13Z000000L3Zj and confirm if you're not matching any of those.

 

We recommend to disable JNPRNS from the adapter properities because of this known issue - https://kb.pulsesecure.net/articles/Pulse_Secure_Article/KB43833/?kA1f1000000fz7V

Re: Windows 11 Pulse Secure Constant Reconnecting and Disconnect

Hey a note for the developers.  I found something strange.  For my organization I must have teams desktop as well as pulse.  Pulse gives me reconnect and disconnect issues (ver 9.1.13 / windows 11), however if I exit teams completely and connect pulse....stable connection.  Its crazy.

Re: Windows 11 Pulse Secure Constant Reconnecting and Disconnect

For anyone working on the Windows 11 - pulse issue;  Here is some additional items I wanted to share in my process of trying to get resolution on this issue;

1. Pulse hates to connect if any other program requires a live internet connection, for example.  I can't get a solid connection with pulse if teams is running or if the internet is live.

2. My solution for now is; I don't have pulse startup with Windows 11 anymore.  If I need to connect I exit teams completely and make sure no other internet based program is running, (i.e. browsers or windows mail)

3. I then open pulse and make my connection.  It stays stable.

4. I have been able to connect to internet and mail after the stable connection, however if I turn teams on connection lost.

 

Obviously this is not a fix!  Could it be a large amount of resources that both seem to pull (pulse and teams)?.  Or maybe this is a tunneling issue? - I thought hardware, bought new 2.5x 10gb ether card and that had no impact.  (FYI - my connection speed is constant at 495 down and 49.8 upload.)

 

Hope this helps to getting a solution.  Please release 9.1r13.1  maybe that is fix?   I only have 9.1.13
