Someone else had this issue (on ios) and was resolved by a client update. It may be worth a look...

@Mick_Ball

Thanks for you reply

As i already upgrade the version from 5.1.7 to 5.2.5 version

Re: Global protect Notification

Mick_Ball — Sun, 28 Feb 2021 10:55:24 GMT

My next step would be to check GP logs, pangps may help...

you can prevent popups in reg but probably best to find what causes the message.

show-system-tray-notifications yes | no

Dear @Mick_Ball

When i run this command it's not working

Please advise

Re: Global protect Notification

Mick_Ball — Sun, 28 Feb 2021 11:41:26 GMT

Sorry for the confusion, that was not a command, that was a registry setting in hkey\local machine to block GP popups if you wanted to...

Dear @Mick_Ball

Thanks for your reply

As we have big environment around 400 to 500 users. we are not able to do in each and every system.

is there is any other solution ?Please advise

Re: Global protect Notification

Mick_Ball — Sun, 28 Feb 2021 13:13:34 GMT

I have no idea as i have never had this message and we have over 6k userbase.

does this happen for all users, do you have only 1 gateway... have you checked the GP logs on the device with the popup and go through the pangps file.

Hello,

This message means you have connected via SSL instead of IPsec, which is typically slower.

Check that you have a rule allowing the application ipsec-esp-udp and ensure that the client side / nothing else is blocking access to the gateway on UDP/4501

Check the traffic logs on the gateway for port 4501 to see if this is being denied on the firewall side (if you log everything anyway).

Re: Global protect Notification

Mick_Ball — Mon, 01 Mar 2021 09:14:04 GMT

@dmifsud Do you know what version of PAN gives this message out?

@Joshan_Lakhani What version of PAN OS are you currently running.

I often see "switched to SSL" in user logs but still no popup for them.

Re: Global protect Notification

Re: Global protect Notification

Mick_Ball — Mon, 01 Mar 2021 09:24:30 GMT

yes but IPSec is failing at some point.. this is what @dmifsud was telling you.

GlobalProtect will revert to SSL if IPSec fails.

(P4912-T7656)Info ( 221): 02/21/21 13:54:18:427 failed to receive keep alive

@Joshan_Lakhani could you confirm software version running on firewall.

Re: Global protect Notification

Joshan_Lakhani — Mon, 01 Mar 2021 09:26:06 GMT

@Mick_Ball

Global protect version is 5.2.5 version

Re: Global protect Notification

Mick_Ball — Mon, 01 Mar 2021 09:31:13 GMT

could you tell me the software version of the firewall]

Re: Global protect Notification

dmifsud — Mon, 01 Mar 2021 09:31:24 GMT

@Mick_Ball Based on past experience this is an "issue" in GP 5.2.5 (Which Joshan is using). I believe it is related to the improved error messages, so a lot of people are suddenly getting this warning thinking it's a new issue, but IPSec never likely worked in the first place.

Features Introduced in GlobalProtect App 5.2 (paloaltonetworks.com)

Improved Connectivity Error Messages for the GlobalProtect App

(GlobalProtect app 5.2.5 and later releases) To enable a better user experience, the GlobalProtect app is now updated to display improved connectivity error messages. With this change, the GlobalProtect app can now provide friendly, informative connectivity error messages to help end users resolve issues on their endpoint themselves to reduce support calls to their Help Desk professional.

Re: Global protect Notification

Mick_Ball — Mon, 01 Mar 2021 09:36:01 GMT

OK thanks for the information. i was not aware as just below that version..

i like the suggestion.. " to reduce support calls to their Help Desk professional".

this new popup will send our helpdesk phones into meltdown.... nice one Palo.

Re: Global protect Notification

Joshan_Lakhani — Mon, 01 Mar 2021 12:56:53 GMT

@Mick_Ball

Paloalto Version is 9.0.9h1

@dmifsud

I have check the security policy and it's created any any.

Moreover i take the pacp but not packet is hit on 4501 port. Can you please advise

Re: Global protect Notification

Mick_Ball — Mon, 01 Mar 2021 13:06:08 GMT

Do you have "Enable IPSec" selected as below.

if yes then your connection will first try IPSec on udp 4501. if at any time this fails then it will revert to SSL (443) and thats probably when you are getting the popup.

try pcap from the start of the connection,

Re: Global protect Notification

dmifsud — Mon, 01 Mar 2021 13:07:00 GMT

@Joshan_Lakhani if it's now showing on the pcap that suggests it's failing before the firewall.

Check the local machine's firewall/other security software, and any other devices in between which could be preventing connectivity.

Also as a sanity check, have a look at the gateway settings and ensure IPSec mode is enabled.
