times out when is proxied

I have searched the forums but none of the suggested fixes seem to work for me.

I don’t know if it helps but I am on an a2 hosting shared server.

When I proxy on Cloudflare DNS then I can no longer use because it times out.

Using my mail server ( works though.

But if I disable the cloudflare proxying of then works fine.

Any ideas?

Here is my DNS setup (domain and IPs changed to protect the innocent):

Port 993 is not supported with Cloudflare.

Please refer to this list to see all the ports that Cloudflare will proxy.

I am not proxying, just but 30 seconds after I proxy then times out…

I see, that is interesting. Is it possible that there is a cached DNS entry that still points to Cloudflare on the subdomain? Otherwise, I’m unsure sadly.

Wow, I flushed my DNS sudo dscacheutil -flushcache && sudo killall -HUP mDNSResponder and it works fine (macOS).

Amazing, thanks… so how did DNS caching stop it working on port 993 but allowed it to work on port 143?

Glad to hear that worked!

Genuinely unsure about how that would have happened.

However, as the saying goes:
