In orbot when I want to add a bridge says the bridge format in invalid. I tried snowflake bridges and obfs4 bridges in different formats, but the problem exists:
Bridge bridgeline
bridge bridgeline
bridgeline
and
bridgeline without obfs4 or snowflake before the IP of the bridge.
The version of Orbot is 17.5.0-RC-1-tor-0.4.8.16 android.
What is the problem?
Update
I tested more possibilities. It doesn’t accept only IPv6 bridges and accepts IPv4s. But when I add an IPv4 bridge and tap on Connect button, says the configuration is invalid and doesn’t conenct.
