I tried everything but still getting this error.
For anyone else having this exact error. After some back and forth with our Security team they were able to 'resolve' this issue by whitelisting the cdn.jsdelivr.net domain.
The issue stemmed from our Cloud security software (Cisco Umbrella) causing a 302 code to be returned when Cocoapods was trying to access that domain. Cocoapods (v1.10.1 as of the time of this response) does not handle a 302 code and throws the error you see in the original post.
You can see the Cocoapods Ruby code throwing the error here: https://github.com/CocoaPods/Core/blob/1.10.1/lib/cocoapods-core/cdn_source.rb#L372-L417
