I really like Zerynth. But when I first google Zerynth I did not find any materials in Russian about Zerynth. Moreover, I could not get to the forum. Your servers probably use blocked IP addresses in Russia. In the browser, this is solved easily by free VPN. I downloaded the IDE and could not install it. Because she also uses these IPs. I bought a VPN just to try Zerynth in action.
But I do not think that a large number of people from Russia will be just as persistent.
It would be great if you could solve this problem.
DIY electronics is very popular in Russia and I think Zerynth could become popular.
