License:

False positive detections:
I tested this app's apk on VirusTotal and confirmed nothing detected as of 2022-11-18. I think I made this app as secure as I can by publishing its source, but it seems that some anti-virus softwares are still warning about this app. I'm sorry to say I cannot handle all false positive detections alone. Your available options may be,

1. Ignore the alert.
2. Submit a false positive report to your anti-virus software's vendor.
3. Build this app from its source.
4. Try another SSTP client.

I hope you will achieve secure communication in some way.

Ratings and reviews

It was working perfectly for almost 3 months.but a few days ago it doesn't work any more. It gets connected for few seconds and then stops. I tried several host names and updated the app to the last release but the problem is still there. I would be grateful if you solve this issue. 🙏

Good and useful app with one critical problem and it is: whenever it gets disconnected, auto reconnect doesn't establish connection to internet, you need to manually disconnect and reconnect everytime. This is frustrating in low coverage or poor signal situations.

Seems simple but always fails connecting to Mikrotik SSTP server that has a self signed CA and Server cert which works from my other SSTP clients without the need for a client cert. Says the error is probably SSL protocol so doesn't work.

What's new

- Implemented custom SNI option
- Implemented a feature to launch the main activity from the tile
- Positioned cursors at the end of text
- Fix confusing term: `Add Trusted Certificates` to `Specify Trusted Certificates`
- Updated dependencies

No need to update if the app works fine.

As always, if there is something wrong, please try reinstalling.
