@brutalbirdie Dear, again: really appreciate very much your effort and time you spent to fix a problem so I can move forward. I hope in future I can reciprocate with you or with the community.
Thank's also to showing me a method that I can use to improve for my future search and go deeper inside problem fixing, but also to know better Cloudron platform.
I think this community is one of main important assets of Cloudron. Also for this, after one year testing, I decided to move everything to this platform, abandoning platform like Cpanel, Plesk, Virtualmin.
Of course, nothing is perfect but we are here together to improve this.
Many thank's again for your help and apologise if we spent effort to discuss about collateral issues that do not concern the subject of the post.
@girish Indeed - definitely Go, not seeing anything in the logs other than say a site not resolving which causes the trigger to fire - nothing to console about the message going out - maybe I can find a debug=true string somewhere.
