Xcode upload error: Failed to open ssh session. (16)

Question

NOTE: We finally uploaded the app but we didn\'t really troubleshoot this issue so I would appreciate if someone could share some valuable insight or experi

Answer 1

After having the same issue I've been able to fix this issue.

To solve this issue you need to:

1. Go to page 6 "System and Network Requirements" from https://itunesconnect.apple.com/docs/UsingApplicationLoader.pdf

2. verify that all of the ports and IP addresses are accessible.

After opening all of the ports from the table, I'm now able to upload my apps.

Enjoy!

Answer 2

I had the same problem when using my company's network because we use a proxy and due to security reasons all the needed ports and IPs reported on the official documentation were blocked. After switching to an external network without proxies, I was able to upload my new app.
