iOS Devices Can't Connect To VPN/Pistrong about pistrong

My first guess: You installed a 32-bit OS on the Pi, and when you updated it recently, the kernel was switched to 64-bit by the upgrade. It turns out that this is problematic, but there's a fix. Here are the details...

First, let's determine if that's really the issue. On your Pi, do: file /bin/ls. if the file command is not found, please sudo apt install file.

If the file command returns:

/bin/ls: ELF 64-bit LSB pie executable, ARM aarch64, ...

Then I'm wrong, so please run pscollect from this github and post the output here (or email it to me if you'd prefer)

On the other hand, if the file command returns

/bin/ls: ELF 32-bit LSB executable, ...

AND uname -m returns "aarch64", then your Pi was gratuitously switched to the 64-bit kernel by a recent RasPiOS update.

The fix is to sudoedit /boot/config.txt. If there is a line with arm_64bit=1 change it to arm_64bit=0. If there is no such line, add: arm_64bit=0. Either way, write the file and exit the editor, reboot, and try the VPN. It should work now.

If it doesn't, I'll need to see the pscollect output.

As far as the iOS SSH application, I use Prompt 2 by Panic, Inc. TBH I don't use it that often, but I've not had any issues with it. I've seen a lot of mentions of Termius, but I've never looked at it.

LMK if the above corrects your VPN issue.

Unfortunately, it doesn't correct the VPN issue. I've confirmed I'm running 32-bit Raspberry Pi OS & it's running a 32-bit kernel and I've also added the arm_64bit=0 line to /boot/config.txt. And running pscollect says the command wasn't found. Another suspicion I have is maybe perhaps it's something to do with the CA file and maybe I just have to recreate it (but it wouldn't make sense as my Windows cert/VPN connection still works)?

And thank you for the SSH app recs, will look into purchasing one after we figure this out 😅

pscollect is a file on this github. Please download/run it (you'll probably need to change the file protection to 755 first), and get me the output.

I've ran pscollect and sent the diagnostics file to you via email. Let me know if you need anything else or if you can't view the file (via GitHub or on email works). Thanks!
