Couldn't register due to: TimeoutExpeption: null

When registering a new collector with a new token I am getting this error when trying to register the collector on the Skyline collector side:

Couldn't register due to: TimeoutExpeption: null

There is a proxy server in place and correct details added in the Network connectivity section (and the tests pass)

Hello Graham,

Welcome to Skyline Communities!

Network connectivity test, only confirm its reachability to proxy and vcsa. However, We require a network to allow upload and download from skyline collector to below links.

To test the connectivity you may run below commands from Skyline VM Console.

curl -v https://vcsa.vmware.com:443

wget https://vapp-updates.vmware.com:443
