Description of my issue
Hello la communauté 
J’ai installé Yunohost sur un Raspberry 3 qui fonctionne très bien avec un domaine OVH et DynDns mais je souhaitais faire utiliser un VPN pour masquer l’IP de ma box.
J’ai un VPN chez PIA (Private Internet Access) et j’ai réussi à créer un fichier .cube qui fonctionne avec l’application VPN Client.
Dès que j’active le client VPN et que DynDns fait son boulot, je perds l’accès au site.
Si je coupe le VPN, tout fonctionne Ă nouveau.
Hello community 
I installed Yunohost on a Raspberry 3 that works perfeclty with a OVH domain and DynDns but I wanted to add a VPN to mask my router IP.
I have one at PIA (Private Internet Access) and I managed to create a .cube file that works with the VPN Client app.
As soon as I activated the VPN Client app and after DynDns is updated, I loose the connection to the website (from outside of my home).
When I stop it, everything is back to normal.
VPN infos:
"server_name": "france.privateinternetaccess.com",
"server_port": "1198",
"server_proto": "udp"

Face à cette erreur, je ne sais pas de quel côté me diriger, certificat ? nginx ? firewall ?
J’ai essayé avec un certificat auto-signé et un certificat let’s encrypt, c’est le même résultat.
Niveau pare-feu, j’ai bien une règle sur le port 1198 qui est créée
Est-ce que j’essaye de faire est-il tout de même possible ? Ou dois-je basculer vers un VPN avec IP fixe ?
Merci Ă tous par avance pour votre aide.
With this error, I don’t know where to look. Is it the certificate ? Nginx ? Firewall ?
I tried with a self-signed certificate and with a let’s encrypt certificate but it’s the same result.
In the firewall, I do have a rule created on the port 1198.
Does what I am triyng to do is even possible ? Or should I switch to a static IP VPN provider ?
Thank you all in advance for your help.
