Describe your issue

Hello,
First I would like to apologize for the potential lack of knowledge that I will probably show, as I’m a total beginner on the use of Yunohost.
Second, I’ve made my best and came across the forum trying to find similar issue as mine, found several guys having problems close to mine but didn’t find yet the answer to my problem, so if I’m wrong on that, sorry again
Finally thanks in advance for the volunteering activities as support, that’s great to see such a community helping.

So here is my problem :

I’ve managed to install Yunohost on a mini-computer that I would like to use as a server at home.
I’ve linked a URL to my server, redirect my ports on my internet box, and set my VPN access.

I can install and use applications on it without any problem : Homeassistant, Jellyfin, Nextcloud etc…
And I can access though any other computers on WIFI (at home, at work, friends etc..)

BUT, when I’m trying to connect through smartphones, it doesn’t succeed depending on the phone used.
The webpage displays : “ERR_CONNECTION_RESET”

My phone (recent Pixel 8) doesn’t give me the access, another Apple phone get the access without problem, some Androids do some other can’t…

It look like a Certificate rights problem but I’m not sure, and I’m not able to find the way to solve this.
My main goal is to get access to my Yunohost using my smartphone on mobile data.

Some precisions :
I’ve done the redirection of ports :
-80
-443
-22
-8095
-9020
-993
-1900
-7359
-51413

Thanks in advance

Does the issue resolve if you disable the vpn?

hi are you use block some something in your mobile, try to install wrap cloudflare and activate on your phone

I will have a look at wrap cloudflare.

So far I’m guessing that something related with Certificate on my phone as :

  • no access granted on my phone in 4G/5G data (no matter what internet browser I use)
  • access granted on my phone on Wifi
  • access on some other phones in 4G/5G depending of the brand but sometimes not

Hi, I’ve tried to setup Cloudflare but I’m struggling to fix it.
Would you accept to detail a bit more your suggestion to help me with my problem ?

Thanks !

Seems like a DNS issue. Have you first tried changing the DNS settings on your phone, or comparing them with the DNS settings on the other phones that can connect to your YunoHost site?
