Suspicious connections of Signal and to ubuntu

[humungus]

Hello,
when I start the software and use the Signal client, there are connections open to amazon servers and the application has a strange name. There is also a permanent connection to ubuntu or ubports open. Can anyone check this please. This seems suspicious to me.

Best regards.

@humungus I've pinged the developer.

Probably Signal uses Amazon cloud. Nothing to worry about.

@humungus,
here is an article, why signal uses amazon aws
https://signal.org/blog/looking-back-on-the-front/
The connection to ubports or ubuntu could be the push-notifications-server.
What do you mean by "strange name"? The used namespace is textsecure.nanuc. The textsecure is the historical name of signal and nanuc us the name of the maintainer.

Best

Thank you for your reply. I was just curious, because the initial key exchange with a friend was not flawless, it needed to be restarted a second time, and also some acknowledgements of delivered messages failed. Anyway thanks again.
