This is likely related to Gas Mask's lack of Apple Silicon support — the networking code doesn't handle modern macOS TLS/ATS requirements properly under Rosetta.

If you need remote blocklist importing on an M-series Mac, SaneHosts handles this natively — it has a catalog of 200+ blocklists built in, and you can also import any custom URL. Native Apple Silicon, actively maintained.
