QAbstractSocket::UnconnectedState(GNSS-SDR Monitor)

[tetsutetsu233]

Hello,excuse me.
I'm a graduate school student in Japan and challenging to get CNR(C/N0) of GPS signal by using GNSS-SDR Monitor.
But,I have been having hard time because I don't know why the error like attached screenshot in terminal display causes now.

In detail,when I put the button of "connect" on GNSS-SDR Monitor display,the error "QAbstractSocket::UnconnectedState" causes.
If its cause is mismatching of port number(GNSS_Synchro port or Monitor_PVT port),I would like to know how to fix the problem.
I'll share screenshot of my preference on GNSS-SDR Monitor and my using file content※.

It has already been three months since I faced this problem.
I would appreciate if someone could give me some feedback.

Regards,
tetsutetsu233
