Cool. A few people's home network doesn't like NostrGram's socket server and so block the port. The great majority of firewalls don't block port 444 by default, but apparently some do. Using that link bypasses the socket server and just uses NostrGram as a regular website instead.

Awesome, thanks! Seems like there have been others who had trouble logging in and switched to different clients. But I’m sure you have a million things to work on sir.
