I have a Heroku app with a free account. I also have a free account in Cloudflare.
I am trying to connect them with a Full SSL connection. In cloudflare, I see the following state:
However, I can't access my website with a secure connection. I am getting an error 525:
I think the problem is with the settings in Heroku but I can't find much information online...
Any suggestions?
回答1:
Use the app URL (appname.herokuapp.com) as CNAME value instead of the domain generated by Heroku.

Have you tried connecting directly to the host with SSL?
Perhaps try running ssl labs https://www.ssllabs.com/ssltest/analyze.html?d=YOUR-DOMAIN-HERE&latest to view which ciphers are supported etc.
I wonder if the cloudflare proxy to the host supports server name indication (SNI) since I presume that on the host end (Heroku) you don't have a dedicated IP.

In the Crypto settings on Cloudflare under SSL, change your value from Full SSL to Flexible
