AWS "connection reset by peer" error when trying to promote a release

Hi since todays morning I’m getting the following error using both web UI and console:

RequestError: send request failed caused by: Post read tcp>54.240.XXX.XXX:443: read: connection reset by peer

(CloudFormation is not aware of any attempt of updating the stacks)

Appreciate any help. Thanks!!

This got fixed minutes later (by itself).
