Description of my issue

I’ve just installed a yunohost instance on a Raspberry Pi on my home network, using the dyn dns service offered by yunohost (domain name of the type XXX.ynh.fr)

I have tried to configure port forwarding on my router (Fritz Box 7530) as follows

I have configured port forwarding only for TCP protocols.

But yunohost diagnosis tool reports errors on every port.

Do you have any clue to solve the problem? Do I also have to configure port forwarding for UDP protocols?

Thank you in advance for your help.

Best wishes,


Nope, TCP forwarding should be enough … I don’t have much clue, I just saw people in the past having similar issues on Fritzbox … Naively I would say “double-check the local IP” but I guess you already did…

Dear Aleks,

Thank you for your suggestion.

Yes, I did… I’ll continue searching for a solution.



Is your server really reachable on these ports?
In order to check that your router config is fine, whatare the results when you test your ports with that: https://www.yougetsignal.com/tools/open-ports/

Dear Benance,

Yes, it is reachable. The test with the previous url outputs that port 80 is closed.

Best wishes,
