Describe the bug

Sometime (once a day or more recently), internet get inaccessible through the wifi. I need to restart ynh-hotspot service in the gui to have it working again.

Context

Hardware: Old laptop or computer
YunoHost version: 11.2.3
I have access to my server: Through SSH | through the webadmin | direct access via keyboard / screen
Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: no

Steps to reproduce

Internet access stops through wifi
I connect to my yunohost thanks to an other connection
I restart the service ynh-hotspot
Internet is back on wifi.

Logs

When I had issue (long time ago) with a vpn that needed to be restarted, I could make a script that was checking if vpn was ok and restarting it if needed but I don't know how to make a script testing if the wifi is ok from within the hotspot.

From what I understand, you are using the hotspot together with the VPN client? The code between these two apps is a bit messy and produces strange behaviors, that's why I made some PR these last days in order to make things cleaner.

When the issue occurs, could you run the following:

iptables -w -nvt nat -L POSTROUTING | grep MASQUERADE

You should get something like this:

 4465  431K MASQUERADE  all  --  *      tun0    0.0.0.0/0            0.0.0.0/0

Indeed, I get this :

aaa@xxx:~ $ iptables -w -nvt nat -L POSTROUTING | grep MASQUERADE
 163K   17M MASQUERADE  all  --  *      tun0    0.0.0.0/0            0.0.0.0/0

Is this what you get when you don't have internet access from your hotspot? Because the NAT is correctly configured there, which means something else isn't working...

Yes, I launch the command when I could not get internet from my hotspot. I only need to launch this command and internet is back from again : sudo yunohost service restart ynh-hotspot

It should be fixed with the latest versions of vpnclient and hotspot apps
