I think part of the problem may be because you’re trying to export your config from the very old version of Syncthing into the current version of Syncthing-Fork. I would try one of the two ways:
Upgrade your Syncthing app to the newest version first, then export the config and try to import it into Syncthing-Fork.
Install a similarly old version of Syncthing-Fork and try to import your config there. Then, if everything works correctly, update the Fork to the newest release.
Also, please to make sure that you don’t try to run both Syncthing and Syncthing-Fork at the same time, as that won’t work without additional tweaking (e.g. setting different GUI ports for each of them, etc.).
If you’re still asked for the password after doing all that, please also try rebooting your device. I’ve personally had an issue in the past where the Syncthing binary continued to run in the background even after uninstalling the app. Rebooting the phone cleared it.
This is weird. The username is “syncthing” and the password is your API key (which you can find e.g. in the config file), so you can probably log into the GUI this way, but the problem is that the GUI is supposed to load automatically without requiring the user to input the login information manually.
@Catfriend1 I’m sorry to bother you, but have you possibly got any idea what the problem may be about?
Yes, you cannot modify those values inside the Web GUI on Android. The crash may be specific to the Fork though, since as far as I remember, in the official app, if you tried to clear those settings, they would just revert to the default values on restart.
In short, the user has to stay “syncthing” and the password has to be your API key. However, the Web GUI itself is supposed to load without asking you to provide any of those, so it does seem to be some kind of a bug.
Using the web gui only is not fully supported by the wrapper but mostly possible.
