Hello, I report here a problem found in QtCreator, starting from version 12.0.0 and and still present on v15.0

I asked for clarification on the forum, and it was suggested that I open this bug report.

https://forum.qt.io/topic/159650/problem-with-remote-linux-device-run-and-or-debug/2

after upgrading to QT Creator 14.0.2 I can no longer run or debug my project on remote target.
Before the update everything was working fine, I did some checks on the configuration level but everything seems ok to me.

The error I see is the following:

I can't figure out what happened between v11.0.3 (working) and v12.0.0 (not working). 

I tried to enabling logs with QT_LOGGING_RULES=qtc.*=true , but found nothing helpful.

The situation is the same with self compiled Qtcreator or installed using Qt maintenance tool.
