Description NiO 2019-04-28 20:05:46 UTC

SUMMARY
Every time I attempt to send a file to my desktop from my phone, I get an error notification on my phone saying "Failed to send file to me@my-machine".  Everything else in both the desktop and mobile app works fine.  I checked logcat and there is an SSL exception being thrown after attempting to send the selected files, see below.  This is a new problem, read additional info at the bottom.

Desktop:
* Solus 4
* KDE Connect 1.3.4

Phone:
* OnePlus 6T  / stock, unrooted, Android Pie
* KDE Connect 1.12.6

STEPS TO REPRODUCE
1. Pair phone and desktop
2. Send a file

This has worked fine for months, the problem just recently started happening.  The Android app updated on March 23rd on my phone, possible regression with the 1.12.6 update.

One extra bit of info: I am able to transmit files from PC to phone without issue, the problem only exists transferring from phone to PC.

Comment 2 droidSumit 2020-07-28 17:57:39 UTC

Same here. Also, while I get the notification that the file sending failed but I got the file (it's in ~/Downloads). 

I also noticed that for Android - Android file transmission it fails for files bigger than 200Kb it may (or may not) send the entire file. My guess(*) is that it also depends on the Wifi connection. Maybe for larger files it may start failing with Laptop - Android too (IRL, not just the notification). 

I tried with a 180 MiB (and again with a 1.8 GiB) and got no problem (of course beyond the failure notification).
