This I find puzzling, they should both be connecting outside via the same wi-fi modem, shouldn't they? The endpoint works absolutely fine from my browser and I'm able to download the file. My gradle.properties file has no proxy settings (as mentioned, I don't use a proxy) So I don't know if it's something https specific More interestingly, I tried another https endpoint and that one failed too. When I test a connection the one above () fails. It is set to 'No proxy' (as expected, I don't have a proxy). I have checked the http proxy settings in File->Settings->http settings. Just to be clear on what has been tried so far: What I find really puzzling is that this seems to be an error that has been plaguing people for a very long time, I have found so many questions on this but not a single answer that is helping me. I have searched a lot and found lots of solutions and tried all of them but none of them don't solved this problem forever such as updating android sdk, cleaning build cache,Invalidate Caches/Restart and also other solutions such as adding android studio to firewall whitelist and etc. In android studio 3.0 and above 3.1.3 and 3.1.4 there is a problem when you want to build your project is that Not able to download files below when Gradle syncĪfter every new updates of android studio i see new issues that takes lots of time to find a solution for it and sometimes you can't find any good solution to solve the problem forever for example: I am getting error while building the gradle (IDE tool version 3.1.3 android) File > setting > proxy > mark auto detect proxy

Gradle proxy settings android studio
