Getting a general error message in managed backups.

I have Snapshot Pro installed and I was able to do a managed backup once with it and now I am getting a general error message. https://monosnap.com/file/6lrP82IV7R33cs6VSEOhDmAKv0A996

Also getting an internal server error when trying to run a regular snapshot. https://static.livechatinc.com/8801096/P83176DKZX/61987f93e75501afd2ecf954b1b543ca/Screen%20Shot%202018-04-30%20at%209.21.39%20PM.png

Please help!
