I have Nextcloud 13.0.2 installed on Ubuntu 16.04 LTS
I can access it from different phones, tablets, LAN & WAN.
The only device I can’t access it is Xiaomi Mi A1 global version with Android 8.0.0
When I try to access server I get message “Connection could not be established”
I can access server from the browser when connected to the WiFi and enter server IP address.
If I use server dynamic DNS address I can’t access it and error message is: “Connection timed out”
This works on any other device I have which tells me that port forwarding and dynamic DNS are working properly.
Any advice how to solve this will be greatly appreciated.
