Thank you for your early reply.
When I installed Webinoly on my Ubuntu server (18.04), I didn’t enable Letsencrypt for my WordPress sites. I only used Cloudflare origin certificate. Therefore, I think there’s no any letsencrypt SSL certificates on my server (if I’m wrong please correct me). I simply generated private key and origin certificate from Cloudflare site and placed them inside the Nginx installed directory separate folder. Then I added each site private key and origin certificate path in each sites configuration file. That’s I have done.
I try to fix this issue by running “sudo webinoly -uninstall” and reinstall webinoly, but no luck.
If my server Webinoly corrupted, are there any possibility to correct it without losing WordPress installation and its data?
