UPDATE -I found out I need to enter in the website as https:// ##.##.##:### instead of https:/:hostname:###. This result times me the spinning loading sign on iPhone before a timeout. No change on Android.
Tl-dr -I have nextcloud in a portainer on a pi4. -I can access nextcloud from my rig and laptop on local network. -cannot access nextcloud from iPhone or pixel phone on same local network.
If need be I can post pictures of where I’m stuck. I also tried the QR code of logging in on the phone but to no avail.
Try install a web server like Nginx. I think the Raspberry Pi OS is based on Debian, so
sudo apt install nginxshould work. Then hit the Pi’s address (no port number needed) and it should show a default page.Bet. I’ll try tomorrow and report back. Thank you!
