Firewall configuration

If a project contains online layers (PostGIS, WMS, WFS, etc), QFieldCloud will try to establish a connection to this services. Sometimes these services are behind a firewall and the system administrators need to allowlist the QFieldCloud IP.

service	IP
app.qfield.cloud	159.100.252.133
app.qfield.cloud	194.182.188.113

PostgreSQL configuration

If your project contains PostgreSQL (PostGIS) layers, you need to configure your PostgreSQL server so it allows connection from app.qfield.cloud IP address.

Otherwise, you will get an error like this:

FATAL: no pg_hba.conf entry for host "185.203.114.168", user "qfc", database "mydb_test", SSL off
WARNING:QGIS_MSGLOG:1 unavailable layer(s) found:

To do so, you need to edit the pg_hba.conf file where your PostgreSQL server is hosted. For more information, refer to recommendations on StackOverflow questions.
