Hello,
I'm using the SDRangel snap version on Ubuntu.

(Version 7.22.9, Qt 5.15.3, 64-bit)

This current link to the OpenSky Flight Map website, obtained by right-clicking in the ADS-B data list: (example)
https://old.opensky-network.org/aircraft-profile?icao24=3b769f

returns to a blank page:

404 Not Found
nginx

The correct link is now: (example)
https://map.opensky-network.org/?icao=3b769f
