VPN disconnects when turning off the screen on iPad

[kamilazat]

Hi everyone.

We have an issue with connectivity consistence ONLY on iPads. I will try to explain it in steps.

==Mobile Access is not enabled on the gateway, so VPN connection occurs over SSL==

1. User opens and connects using Capsule Connect. Everything works properly.

2. User turns off the screen and goes away for 10 minutes. We tested for 10 minutes because tunnel doesn't drop in, say, 4 minutes.

3. Capsule Connect logging seems to be stopped during these 10 minutes.

4. When the user comes back and turns on the screen, VPN indicator is visible on the notification bar, but there is no traffic (verified by tcpdump on the gateway).

5. The moment user goes to the Capsule Connect application, the VPN timer seems to reset and starts from 00:00.

6. The traffic seems to ONLY start flowing when the user goes back to some other applications that communicate with internal resources. This is again confirmed by tcpdump.

We already have updated to the latest iPadOS 18.3.2, and on the gateway we have R81.10 JHF Take 172. We can see that for the time the screen is off on iPad, Capsule Connect stopped logging (no logs with the relevant timestamps during that 10 minutes). And, sadly due to log rotation (yes, we missed that part), we lost the relevant vpnd logs on the gateway.

Before organizing everyone again to conduct debug, changing the number of vpnd.elg files in a maintenance window and run another lap, I wanted to ask if anyone has dealt with a similar behavior. This doesn't happen on Android, but happens on all different versions on iPads. We need to understand if this is a Check Point issue or an iPad issue.

Cheers!

I could have sworn I saw someone had this issue before and they posted about it on community and it turned out to be some setting on Ipad that was causing it, just cant remember what : - (
