Hello!
OpenVPN over UDP and WireGuard are blocked on most (if not all) China residential lines. You need the following connection mode:
OpenVPN
protocol TCP
port 443
entry-IP address 3 (three)
When you run Eddie you can change connection mode on the "Preferences" > "Protocols" window. Uncheck "Automatic", select the proper line (the selection is confirmed by highlighted line) and click "Save".
Kind regards
