This site can't provide a secure connection:

My website is showing that “This site can’t provide a secure connection” whenever I am changing DNS to proxied. I tried changing many settings but nothing happened. Please help me with this.
I will attach a screenshot. I don’t want my website to get offline for a long time. Please help me in this case as soon as possible.
Currently, I am using Google Cloud.

Hi @apksforfree0,

The error “ERR_SSL_VERSION_OR_CIPHER_MISMATCH" in Google Chrome prevents access to the site because it detects an issue with creating a valid connection to your site. This may be a temporary issue, and should resolve itself within 24 hours. If not, grey-cloud/deactivate Cloudflare so that the website uses the origin’s SSL certificate, see How do I temporarily deactivate Cloudflare? Activate Cloudflare again in 24 hours and try to access your website to see if the SSL certificate has been successfully deployed.

Other successful troubleshooting suggestions and more details about the error can be found in this Community Tip.

Thanks for your reply. I have to pause the Cloudflare for 24 hours that’s it. But I am using Grey cloud for a long time. The issue did not resolve from my side. Whenever I turn it into proxied my website starts creating problems.

Did you try steps 2 and 3 in the tip I linked to to restart issuance and try a different validation method?

Currently, I have done it to the grey cloud and I have paused the Cloudflare for my website.

After pausing the Cloudflare on my website and changing grey cloud to proxied the same problem is arising that “this site can’t provide a secure connection”.
