IPtProxy/Onion Browser: Snowflake client just stops with errors when bootstrapping Tor on iOS (and therefore the whole bootstrap)
We're experiencing a lot of instability with Snowflake on Android and iOS.
Esp. on iOS, I always seem to get only the "unrestricted" types. What exactly are the preconditions, to get to the "restricted" snowflakes? Is there something we can do?
Latest IPtProxy currently uses Snowflake at this commit: https://gitweb.torproject.org/pluggable-transports/snowflake.git/commit/?id=af6e2c30e1a6aacc6e7adf9a31df0a387891cc37
While trying to understand, why Snowflake connections are often delayed a long time or not happening at all, I experienced random stops of the code. This is esp. on starting up Onion Browser on iOS.
E.g. see the 2 different logs below.
(It's Onion Browser, Tor and Snowflake combined.)
That's all. That's not just a part. After the last log line, everything stopped. (If the user wouldn't change bridge settings, that is...) The change is about 50/50 that it just stops.
Do you have an idea, why that happens?
Interestingly enough, this seems to happen on a real device way more often than on a simulator on an Intel MacBook Pro running Big Sur. (Note simulator vs. emulator!) So that might point to a timing issue?
This is our config:
https://github.com/OnionBrowser/OnionBrowser/blob/2.X/OnionBrowser/OnionManager.swift#L245-L248
Is there something we can do to mitigate this in IPtProxy? Some catch-exception-and-restart or something?
