When I start Orbot up on my phone in VPN mode, it gets stuck just "starting". I've left it for up to 10 minutes but it ends up going nowhere. I've tried using bridges and changing my TOR identity, but to no avail. Weird thing is though, sometimes it does end up connecting fine, at the same wifi, using what I believe to be the same settings. Is there anything that could be different that's preventing me from connecting?
I have the same problem, and the only way I've found to make it work is to in the device settings force stop and then clear the app data and cache then start the app every time I reconnect, which is kinda annoying, but still worth it for the protection it provides.
