As of version 60.5.0, Outbound Proxy options in Tor Browser Android are not working. It never worked from the beginning of TBB Android. In Orbot, it works fine.

Could you give us some steps to reproduce your problem?

In integrated Orbot, Settings -> Outbound Network Proxy (optional), set TYPE HOST PORT, e.g. socks5 1080. It's expected to use socks5:// as outbound proxy, but it's still connecting to relays directly. Tor relays are blocked here so it can not reach any relay without outbound proxy.
Again, it's working fine in standalone Orbot, which I use Orfox with.

Does Orbot work for you if you don't use an outbound proxy but bridges instead (and I assume you did mentioned just as an example address and not the actual one you entered, right?)? Or are you in, say, a corporate environment that allows traffic only through a central proxy first?

The integrated orbot is ignoring outbound proxy, simple as it is.

Replying to zero_trust:

The integrated orbot is ignoring outbound proxy, simple as it is.

Note, this one is going away soon. However, I'll leave the ticket open to track the need for proxy support in Tor Browser for Android beyond that. Currently our new UI (developed in #28329) does not offer that option. (Even though I still don't understand if you really need a proxy or whether just bridges would work for you as well)

Yes I do need to connect to a proxy first, like a corporate central proxy. Even if bridges work for me, it does not solve the OUTBOUND PROXY IGNORED bug.
For whoever can access Tor infrastructures directly, this bug is not important and hard to figure out . You can try

  1. Use a nonexist proxy as a outbound proxy, integrated Orbot should still connect correctly.
  2. Put the phone behind a firewall with only access to one proxy, integrated tor should not connect.

For standalone Orbot, it should behave the opposite.
