I ran a diagnosis and met these two alerts

I have tried to configure DNS according to the link: DNS zone configuration | Yunohost

I am no savvy on this, so I could easily have done something wrong. Also, there were a few of the settings which I was not allowed to do (I got the impression that for some types of setting, only one is aloowed).

You need to open those ports in your router (TCP for 4443 and UDP for 10000) and forward them to your ynh server.

How and where can I do that?

Edit: In my router? That is the router in my home network?

Yes. See here Configure port-forwarding | Yunohost

But I am not hosting from home. I rent a VPS at Hetzner. Should I configure something on that VPS?

Ok. Is there any firewall in your console ?

I am trying to figure that out now.

It appears that I have not created a firewall for this server.

If I create one, this would be two inbound rules I would have to make, right?

Yes but I don’t know that hosting provider, so it will be difficult for me to guide you more specifically.

I have now made these rules:

I am running a diagnosis on my yunohost server and it takes forever with no apparent progress…

I logged out and now my yunohost login page will not load

I guess that if you set a firewall you also need to forward port 443, 80 etc ?

As soon as I deleted the firewall, I could load the yunohost login page again

How would I know all the necessary rules?

You can first try with 80 and 443.

It seems to work

If it doesn’t fix the port opening, I would remove this firewall (I thought you already had one) as I’m not sure why, by default, Hetzner would be filtering ports 4443 and 10000.

Now I can run the diagnosis and get this:

On my Hetzner VPS I have these rules for my firewall:
