Connection refused during building process in official fdroid server

1

I’m looking at the reason why one (Android) app of mine wasn’t updated for some days. When I look at the build log, it says the build has failed (for the most recent two versions).

The error happens when downloading https://dl.google.com/android/repository/addons_list-3.xml, though the final failure reason is not:

The first log says:

The second log (4 minutes after the first one) is almost the same as the first one, though the final error is not the same:

That seems strange (at least to me). Does anyone encounter the same issue?

(p.s. I have CI on the repo, and the CI can build the app successfully.)

Looks like a temporary network glitch.

Another (two) automatic building attempt is triggered today, but the result is still “failed”.

One (the one for a newer version) of the errors is:

* What went wrong:
A problem occurred configuring project ':app'.
> Failed to find Platform SDK with path: platforms;android-27

The other one is (yes, that’s all):

== Installed Android Tools ==

Still looks strange…

I’ve seen those failures. No idea what happened. Anyway, they’ll be retried.

The error now seems to be fixed to:
Failed to find Platform SDK with path: platforms;android-27

Maybe it’s similar to Failed to find target with hash string 'android-25', though android-25 is actually installed - Stack Overflow ?

Download the sdk and upgrade gradle to 4.1

Just find the issue is located:

Thanks guys.

Is anyone is interested in a quick patch to similar problems, this commit may be a useful example.
