I would suggest using keychain. I seems to make everything so much easier and hopefully safer when accessing Hive sites. In there you could try changing the node you access it by. I have had the spinning wheel many times but a refresh seems to sort it. Things are still a bit glitch since the last hardfork and the nodes can sometimes be the issue.
Thank you. I'll probably give the keychain a try, and then change my password/keys after I'm done needing to access Steem engine. Appreciate your feedback.
