Describe your issue
Hello! We are getting closer to the holidays, I hope that someone can still help me, otherwise I will wait until next year. Happy holidays anyway 
I have a yunohost command that halts and needs to be manually stopped, similarly to this thread and this thread.
Context: While trying to install a second instance of the app “Reverse Proxy”, I was creating a new subdomain (with a SSL certificate) through the webadmin interface. I’ve started the command and the modal with the title “The server is processing the action…” and the pacman animation showed up.
Unfortunately it halted at “Registering account…” and after sleeping on it for a night it is still there after logging back in. Trying to run commands from the command line is of no help since they have to wait for that same command to finish.
How can I kill the command?
Relevant info
I took a look at the source code hoping to solve the issue by myself, and I’ve found that log line here. It is probably halting while making a http request, but I don’t know enough about it in order to understand what’s going wrong.

I’ve also found this this thread. The line 127.0.0.1 yourdomain.com is already present in /etc/hosts/, and the last diagnosis results don’t show any particular problem.
Thank you to anyone who can help me
