YunoHost version: 4.0.8.2
I have access to my server : Through SSH and through the webadmin
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no
Whenever I start the diagnosis menu the server seems to hang and does not respond. After restarting yunohost-api from ssh everything works fine again.
What happens if you run this from the CLI with something like
yunohost diagnosis run --debug
I get the following output. There are longer sections where nothing is happening. After some timeout it seem that some DNS stuff is happening. It took some time but finally finished. Is it ok to run about 7 minutes?

Ehh i guess it can run for 7 minutes for many reasons but that sounds excessively long … I would expect 1 minute max.
Naively I think this may be due to some timeout issues … maybe something to do with the dns resolvers in /etc/resolv.dnsmasq.conf - or maybe the lack of IPv6, something like this :s But difficult to tell exactly without being able to tests some stuff manually
I guess you could try to check if one of these commands takes longer than the others

Yes, I agree. It’s hard to support such cases.
All the commands you gave to me worked extremely fast. The server runs on a Hetzner-VPS. Never had any networking issues with them. It’s not a big problem for me as I am running the diagnosis tool not often. However I wanted you to know about this as it seems to be not normal.

While diagnosing it with strace, it seemed like the 80.67.190.200 DNS server was timing out. I edited the /etc/resolv.dnsmasq.conf file to only contain google’s dns and now the diagnosis works
U wot m8
I know, I don’t like google as well, I just wanted to quickly check if another dns would fix it, and that’s the address that I remember (8.8.8.8).
Anyway - the issue was that one of the DNS servers times out. For some reason the script insisted on using 80.67.190.200. The dig command worked before changing the dns, but the diagnose script didn’t.
Removing that faulty dns server from config resolved the issue for me
