Just pushed an update to NostrGram that should provide seamless reconnection if you're out in the wild (or just in a spot with bad reception) and the client gets disconnected from the socket server. Now it should pick back up and resubmit any requests that it was waiting on. Reconnects are also much faster so you might not even notice.
Discussion
interesting! I have a question:
How can save all the INFO of NortrGram, for example, to give more "healt" to the network? In a node?
If you mean how do you save your data, you can download it from your profile. Just click the download (down arrow) icon. It's in the JSON format that a relay should support.
