Hi,
This is most likely due the fact that S1 and S2 parameters in .conf file are zero. We are planning to update the generator and change variables. However we are still testing and collecting feedback regarding this change.
Right now if you want to speed up the update try modifying S1 and S2. It can be any number from 2 to 10 for both parameters. Let us know which one you used and if it worked or not.
Simply download AmneziaWG .conf via generator and edit .conf file with any text editor or inside AmneziaWG client. Down below is a example.
Thank you. But it didn't help. I tried few times with different numbers. I edited numbers inside AmneziaWG on iphone.
