After 1.4.0 release we found some minor issues, it's wise to update your instance to the latest 1.4.1 patch release if you didn't had already.
More info at: https://github.com/MbinOrg/mbin/releases/tag/v1.4.1
If you didn't follow the 1.4.0 release notes yet, then BE SURE TO carefully follow the those upgrade instructions as well: https://github.com/MbinOrg/mbin/releases/tag/v1.4.0. From 1.4.0 we changed how the transport messenger (AMQ) is working on bare metal instances.
We are planning soon for a new minor release (v1.5.0). Thanks for using Mbin!
Personally, I'm also planning to setup mbin.melroy.org which will replace this instance. However, ActivityPub will see that new domain as a totally new instance. Migration is not straightforward too bad.
