Which means there is a problem on the server side.

Make certain that the URL you are connecting to looks like a valid URL. For example, you can do something like:
确保您要连接的 URL 看起来像一个有效的 URL。例如，您可以执行以下操作：
NSLog(@"the url I am connecting to is %@", [myURL absoluteString]);
And see if it matches what you were expecting: https://staging.something.com/api/.
看看它是否符合您的预期： https://staging.something.com/api/.
If it looks really wrong, like "apihttps://staging.something.com", then it's something that you can easily fix.
如果它看起来真的是错误的，比如“ apihttps://staging.something.com”，那么你可以很容易地修复它。
If you are getting this problem all the time, you should probably reach out to the owner of the service you're trying to use and ask them for assistance.
如果您一直遇到此问题，您可能应该联系您尝试使用的服务的所有者并向他们寻求帮助。
