I’ve signed in cloudflare for a free plan, and I’ve setting up everyting as required by Cloudflar including DNS (I used the dns servername from cloudfare) , and used SSL full. Then I’ve decided to delete my site from Cloudflare. After deleting the site and changing the DNS name server to the original (DigitalOcean nameserver) I have encountered a problem with SSL , when I write https://bioinfexperts.com1 , I got this error ( This site can’t provide a secure connection bioinfexperts.com sent an invalid response. ERR_SSL_PROTOCOL_ERROR)
When I test the SSL certificate using SSL Lab test, I get A, the SSL. SSL Certificates are exists in the server. Ive tests using openssl command
I really dont know where is the problem. Any help to solve this issue is appreciated
P.S ■Wordpress site ■Server: ubuntu 16.04 LTS / digital ocean. ■SSL: letsencrypt.
