ERR_SSL_VERSION_OR_CIPHER_MISMATCH

Vaultkeeper

My forum URL is https://kickboards.flarum.cloud/

i set up a domain and I was expecting to access my site at www.kickboards.online over HTTPS, but I received the following error:

This site can’t provide a secure connectionwww.kickboards.online uses an unsupported protocol. ERR_SSL_VERSION_OR_CIPHER_MISMATCH

I checked the browser console, and there were no additional relevant logs displayed. However, the issue seems to be related to SSL/TLS configuration? any ideas on how to fix this?

Vaultkeeper please, CNAME to cname.freeflarum.com instead, not kickboards.flarum.cloud, then repeat the domain linking process (see the documentation for more information: https://docs.freeflarum.com/en/tutorials/custom-domain/)

Vaultkeeper

SKevo thank you so much for the help! I did what you said but now I’m getting, do i have to wait for it to populate? The DNS is saying ‘cname.freeflarum.com.’ on DNS checker.

"This site can’t provide a secure connection
www.kickboards.online uses an unsupported protocol.
ERR_SSL_VERSION_OR_CIPHER_MISMATCH
Unsupported protocol
The client and server don’t support a common SSL protocol version or cipher suite."

Vaultkeeper I have updated your domain in your FreeFlarum settings, the forum should now be available at https://www.kickboards.online (if it’s not, please try accessing it in the Incognito mode, as browsers cache redirects etc.)

Vaultkeeper

SKevo i tried in incognito and still get error?

SKevo

Vaultkeeper I think it just needs to propagate all over the internet. The forum is accessible on the custom domain for me (also in different browsers and devices, so it’s likely not a browser caching problem).

If the issue still persists after 24 hours, please tell me so that we can find the root cause.

Vaultkeeper

i was playing with the settings so may have messed it up again. not sure

Vaultkeeper

SKevo hmm the only issue is my forum is unusable till it populates right?

SKevo

Vaultkeeper yes, because the old URL redirects to the new one. Since the forum is accessible at the new domain for me, I suspect it either takes some time to take effect or there’s something else wrong at your side

Vaultkeeper

thank you for all the help BTW

Vaultkeeper

SKevo You are amazing. Thank you again for all the help with this.
