My gr_satellites version is ...

And I am running under Arch Linux. (Although the same result occurs with Ubuntu 23.10.) Have I found a bug, or did I miss use gr_satellites? Thanks in advance.

Thanks for reporting. This is a bug. The problem is that if telemetry submission is enabled, gr_satellites tries to authenticate to the BME telemetry server at https://gnd.bme.hu:8080. This server is not active at the moment (I'm not sure if it will ever become operational again), so the connection fails. I have fixed this bug by making this not a fatal error. The bug fix is now in the main branch. A workaround for older versions of gr-satellites is to disable telemetry submission in $HOME/.gr_satellites/config.ini.
