Describe your issue

Hi!
I have changed recently my ISP, but cannot update the redirection of my ynh domain to the new IP address… this should be handled automatically by YunoHost, but I have an error message stating DNS record not valid, and asking to try forced update ( yunohost dyndns update --force), but this does not work.
any idea ?
regards

a few additional comments in order to be more specific :

  • I have not only changed of ISP, but also added one router between the ISP Box and the network, in order to create two separate VLAN, one private «Home» and one more «public» for a rented area.
  • I have opened the relevant ports 80 and 443 in the ISP Box, and directed the incoming traffic to the network router
  • on this router, ports 80 & 443 are also opened and traffic is directed to the IP address of the YNH RBPi
    Is this additional step between the incoming internet traffic and the YNH server a possible cause of the problem ?

Can you disable ipv4 on your router in the wan settings?

thanks, but I am not sure to understand : the first modem/router from my ISP is connected to only one equipment, a second router in charge of organizing the network in two VLAN, one private (where YNH server is located) and one for the public area… therefore, I need the first modem/router to have its DHCP activated to grant an IPV4 address to the second router, correct ? and these are LAN settings I guess, not WAN. Furthermore, I see no WAN settings access in the first modem/router… Sorry if these are newbies questions, but I am not familiar with networks intricacies!
