I am a newbie to nextcloud. I have my nextcloud running on my desktop running lubuntu 18.04 and installed NC 15 (with snap) I believe (can’t remember because I can no longer access it) till the time I changed my internet provider. Now I can’t access it any more. I had the static IP for my server as 192.168.0.XX and the new internet provider IP I want to change will be 192.168.1.XX. More over I want to change from wired connection to wi fi because there are no cables running up to the server any more. Please help.
