Cannot import ovpn file

[ystr]

I cannot setup connection after reinstalling OpenVPN Connect app on iPhone 5s with iOS 11.1.
I have tried to import .ovpn file using iOS share feature from Readdle's Documents app, Files app and even email attachment. OpenVPN app starts and nothing happens. No alerts, warnings, options and so on, just "WELCOME TO OPENVPN".
My .ovpn file is valid and working on my Mac and Ubuntu machines. And it WAS working on iOS earlier. Any help would be appreciated.

I have the same problem. App is just shows help, no error message. I am using iCloud drive and open in OpenVPN.

we had a couple of reports about this, but we have never been able to reproduce the problem.
All the people reporting the problem have said that at some point it started working again, like if iOS was preventing the file from being opened for some reason, but only temporary.

Does this happen with every profile?

OK, I think I figured out the problem. When sharing using iCloud drive from the files app. Apple places '~' into the filename, which OVPN may not allow. Sending it through email solved the issue. I think some error handling would help. Thanks for the reply.
