Re: nginx service don't start after upgrade from v14
I had loads of issues with NGINX not starting due to SSL key not matching the certicate or the format of the certificate. Suggest you look at the NGINX error.log to see why it didn't start. Hope this helps...
Re: nginx service don't start after upgrade from v14
After applying all the Windows updates, I've removed v14 and install back v15 with success. Now nginx service working fine and I can access 3CX Web console.
