Potential bug in Android app - Create from scratch flow

Potential bug in Android app - Create from scratch flow

[Dana White]

I’ve spent two days trying to connect from Android (Galaxy S10) to EdgeRouter 12 w/WireGuard app. 

I was creating the tunnel in the app manually via the Create from scratch flow. Could not get it to connect.

No problems connecting from Win laptop w/the exact same config. 

Finally (thanks to someone on #wireguard irc) I tried imported the exact same config into the app, and it worked immediately.

It looks like there may be a problem w/the manual entry process. At least that was my experience, repeatedly. App is current version, just installed for the first time two days ago.

Thanks.

Dana

Don't use the same config from two devices. One device :: one private key.

Create it manually, and then export it to a zip. Look in the zip and
see if there's any difference between that file and the one you
imported from the windows app.

Thanks. Using the config was just to test the import process on Android w/a known good config, deleted thereafter. 
	
From your reply sounds like you haven't seen this issue w/the current version of the app? Are you able to manually create and use a new tunnel on the Android app successfully? 

I had another member of the EdgeRouter community note that he had what he thought was a similar problem recently w/the Android app but didn't take the time to follow upon it. 

I'll do as you request and get back.

OK, operator error once again is to blame. 

My router public key in the config had a single digit missing. 

The really odd part is that I can't understand how that happened, as I copy/pasted the router public key from an existing config (that still works and has the full correct key) because there was no way I was going to type out something that long/difficult. I do have problems with my mousepad on my computer sometimes jumping the cursor around when my palm hits it and sometimes messing up what I’m doing, but no idea how that could account for removing a letter and not leaving a space. 

But egg on my face is egg on my face, what can I say. 

Bowing and backing away in shame. 

Thanks for the suggestion to export/compare, that was what allowed me to see the issue clearly.
