parse - swift unauthorized error - ios

Question

I'm new to iOS software development and swift and I'd like to make an app that is similar to instagram. For this I created a VM instance in google cloud with the Network tags parse-1-tcp-443, parse-1-tcp-80. I ran the code above in the newest version of xcode and got those errors. Why do I get unauthorized error when after logging in username, password url are correct?
Allow Arbitrary Loads is set to yes in info.plist
Thanks in advance!

If I write "http://35.19.10.151/" instead of "http://35.19.10.151/parse" I get this:
