Thank you Gentlemen.
This is very strange in that it has started working as expected! After a power cycle it just started working!
I had spent much time on this working on getting the callback right. With all the correct settings in WebTop config still seeing this error in the onlyoffice/nginx error log - which was based on the SSL Cert and it trying to use “http://127.0.0.1” - I had run ‘supervisorctl restart all’ after any changes and did reboot a couple of times:
*331 connect() failed (111: Connection refused) while connecting to upstream, client: 202.*.*.*, server: , request: "GET /5.4.0-21//doc/b451231a846ca032eb3c/c/info?t=1574378457171 HTTP/1.1", upstream: "http://127.0.0.1:48000/doc/b451231a846ca032eb3c/c/info", host: "office.**.com.au:8082", referrer: "https://office.**.com.au:8082/5.4.0-21//web-apps/apps/spreadsheeteditor/main/index.html?_dc=5.4.0-21&lang=en_EN&customer=ONLYOFFICE&frameEditorId=ext-comp-1781-deplaceholder"
I didn’t change nginx settings at all so am still confused as to why it started working all of a sudden!! I’ll go back to start again (I have a snapshot) and will document for HowTos - assuming it works correctly this time.
@mrmarkuz : It isn’t a separate server install, it is your module and as per your instructions - thanks again. Yes, I did need to increase the password key to get started, that was the first obvious point in making it work from webtop.
