Tor has successfully opened a circuit, but did not acknowledge serving haven's port 8888 despite being setup.

My tor browser[1] failed accessing Haven's logs[2] on the onion server hosted by "Orbot: proxy with tor" [3].
(On the point of reporting this, I discovered[4] that Haven's servers was also accessible on localhost:8888. I suggested on a pull request[5] to document that in the help text hovering in the app.)

The server is running well on localhost:8888, and it is now serving me content through a port forwarding.
I did never see orbot's warning "An app wants to open hidden server port 8888 to the Tor network. This is safe if you trust the app."[6].

[5] https://github.com/guardianproject/haven/pull/289
[6] https://github.com/guardianproject/haven/issues/175 ; it would be good to also document that message in a troubleshooting guide.

Start by reviewing the Tor Browser and Orbot versions in the report, the localhost:8888 behavior, and the referenced issues #230 and #175 plus pull request #289. Reproduce the missing port-8888 acknowledgement if possible, then determine whether the behavior needs a code fix or clearer help and troubleshooting documentation.
