Since the last or penultimate update, the OpenVPN connection with IOS (MAC and Iphone) no longer works for me.
Android and Windows are no problem. Download data import and it works.
Unfortunately, IOS still seems to be a bit more complicated.
I have tried these methods. (Except the one without password, which is not an option for me)
Correct, the instruction mentioned by @nightman no longer works. However, this tutorial has been effective for both Android and iOS devices, based on my last check a few months ago. I authored it as an alternative to the wiki tutorial. While I haven’t updated the wiki due to the lack of energy for the work involved in reaching a consensus there, I find the forum more convenient for sharing such guides. If you need any further assistance, feel free to let me know.
