Hi Farank

Can you add some more info on your issue?

Can you upload the logs from Appium Studio and upload them to google driver?

Thanks Tom for helping me. Right now, I found the problem. I ran appiumStudio in my workplace computer which set proxy on, and this proxy prevent from connecting. I changed it, and my problem is solved.
Thanks a lot.
