signal-cli not working anymore

Hello.

I'm using net-im/signal-cli in order to send automatic messages. I now 
realize it has not worked for the last two weeks.

Whatever command I give, I always get the same error:

> % signal-cli receive
> INFO Manager - The Signal protocol expects that incoming messages are regularly received.
> Error while checking account +393516910222: [422] Bad response: 422 

Searching for this, turned out nothing (except a wontfix/closed bug with 
absolutely no useful info).


I know there is no maintainer for this port, but is anyone using it? 
Does it work for you?



I've applied the fix from:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=266916

This helped in the past.
Is now the port too old?

Has anyone tried working on updating it?
If so, what are the problems blocking such an update?


  bye & Thanks
