كلاود فلير CloudFlare توقف Subdomain لا يفتح بسبب DNS
Subdomain not working - Subdomain Need adding DNS record in Cloudflare
Subdomain is not working after creating with cloudflare
My subdomain stopped working after I changed my DNS to CloudFlare
Sub-domain with www get ERR SSL VERSION OR CIPHER MISMATCH

المشكلة :

ان sub domain لا يفتح اطلاقا او بيفتح بدون www ولا يفتح بـ www
كلاودفلير يدعم بدون www فقط واذا اضفت www لن يفتح
وحل المشكلة هو الغاء البروكسي على www. اى جعله رمادي وانتظر قليلا
غير ذلك هيكون شراء شهادة من كلاود فلير

I have subdomain like test1.domain.com 1, test2.domain.com 3 ,
all without www and with https is working find https ://test1. domain .com > working
https ://test2. domain .com > working
https ://www,test1. domain .com > not working - error - ERR_SSL_VERSION_OR_CIPHER_MISMATCH
https ://www.test2. domain .com > not working - error - ERR_SSL_VERSION_OR_CIPHER_MISMATCH

حل المشكلة :

يجب ان يكون هناك 2 من Record من نوع A لكل من
test.yoursite.com و www.test.yoursite.com
كما فى الصورة التالية

سواء تم تطبيق CNAME او A داخل DNS يجب ان يكون هناك Record لـ www.test
مع الغاء البروكسي على www.test اى جعله رمادي
وترك test. الاخر برتقالى كما هو مثل الصورة بالضبط

ملحوظة : قد تحتاج الى حذف الكاش من الكمبيوتر و كذلك من الكلاود فلير

This tutorial post covers the first steps you should take if SSL is working on your main domain, but not on a subdomain.
1. Is there a DNS record for it?
Check the DNS app in your Cloudflare dashboard to see if there is a DNS record there for that subdomain.
2. Check that the DNS record is working correctly
You can use a tool such as https://www.ultratools.com/tools/dnsLookup 294, enter the subdomain.domain.com that should be working and check that DNS records are found for it.
3. Check that the subdomain is not too deep
Cloudflare universal certs cover yourdomain.com and *.yourdomain.com, this means they can cover sub.domain.com, but can’t cover www.sub.domain.com or sub.sub.domain.com. If you need a subdomain that isn’t covered by the universal cert, you will need to purchase a dedicated certificate.
There is more information on this at Subdomain too deep 108
4. Check that the DNS record is set to
In the DNS app in your Cloudflare dashboard, check that the DNS record for your subdomain is set to , not .
5. Check that HTTPS doesn’t work
If you manually enter https://sub.domain.com, does it load with the Cloudflare certificate? If so, you are probably not forcing HTTPS, enable ‘Always use HTTPS’ in the SSL/TLS app of your Cloudflare dashboard.
6. Do you see a certificate from your server?

If you see a cert from your server rather than from Cloudflare, you may be bypassing CF and connecting straight to the server. You can also check for Cloudflare headers in dev tools. If you are not going through Cloudflare, this may be a local caching issue.
