Rebuild has worked now but haven’t gotten mail receiving to work yet.
YAML is good set with domain even with rebuilding mail receiver still states base url as “discourse.example.com” instead of specified domain, that seems like there is a problem with that.
Hopefully will be able to figure out how to make this work, if anyone has any ideas about what problem may be would appreciate ideas about how to make this go.
There is an error: ERROR: Can't find Ruby library file or shared library pups
Have gone through steps of guide: Configure direct-delivery incoming email for self-hosted sites with Mail-Receiver - documentation / sysadmin - Discourse Meta
Edit: after another rebuild correct record has updated and mail receiving works!!!
