I was running 0.9.19.xxxxx happily on several PCs (a mixture of W7 and W10 versions) until I decided to take care of the "license expired" message and looked for new version. Installed new version and on every PC I get this. The "fix now" and "start protection" buttons do nothing. One of the computers is vanilla, never seen a Malwarebytes product, no proxy, no crazy firewall rules. MB3SERVICE logs at the bottom.
