&lt;p&gt;Are you still getting&amp;nbsp;&lt;span&gt;Failed to fetch available toolchains.&amp;quot; and the pop-up you mention&lt;/span&gt;&lt;span&gt;?&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;If you are, can you open the developer console in the Toolchain Manager (CTRL+SHIFT+I). Do you have any output in the console ?&lt;/p&gt;
