Fisrt of all:
where can I find my submited tickets on https://dash.cloudflare.com/
I’m pretty sure I’ve submitted some question but I can’t find them anywhere, like an area where all the messages go.
Ok, and that arised since I was looking for a reply about not being able to access my URL since I change the servernames 
so what now?
I contacted my domain provider and they told me that right now is all in Cloudflare’s hands, so…where should I ask for help
That looks like you don’t have all necessary DNS records here. Your DNS page here should have all the same DNS records as your host.
ok, thank you very much
I’ll check this
ok, how do I know which DNS records I’m missing? I can see I have many DNS records over there
OK something strange happened… My sub domain is now working… I can now access my personalized url… but my original domain has an error
For the first time user
Imagine, you’re coming from a cPanel based hosting. You have many subdomains.
You entered domain in Cloudflare and assumed all records are already there. Exactly, this is mistake.
You must manually verify either all your records exist or not. Sometime, a few records goes missing.
How to verify
Then update nameservers, not without above steps.
all right…so my domain is from namecheap…I go to namecheap. then I go to domain list… then I choose my domain and click on “Manage”. Then I choose Advanced DNS… and then it doesn’t look like it always looked before I got into all this cloudfare stuff 
I’m lost at this step, I don’t know what to do next.
I used to be able to watch a list of my CNAMES and everything…all I can see now is: host records, dnssec, mail settings, personal dns server, and that’s it
You can contact Namecheap support and ask them to remove URL forwarding.
Or, if you’re not expert in these stuffs, it’s ok. Just ask them to restore to previous nameservers. That’s it.
One question
If no, you also need to make sure to have one before starting to use Cloudflare.
Supposedly yes. was one of the first things I did when aquiring the domain…
OK, here’s the thing. I aquired the domain, and used it for my site. But then I’m using a webkul feature app that had its own url, and there was this tutorial about “personalizing my url”… so that’s how I got into all this…
I’m going to try this:
You can contact Namecheap support and ask them to remove URL forwarding.
You are being so so kind, thank you so much!
It would be better to confirm it first. Because, I don’t want you to use insecure - flexible SSL, and use Full or Full Strict that will avoid redirect loop case as well.
ok, Is there a way I can confirm it by myself or do I have to contact namecheap support?
is flexible insecure?? Oh my… I think … I better ask to have everything restored as before… This was supposed to be for acquiring more security and it looks like I’m getting more holes in the process…I think I’ll stick to the non personalized url 
At least not until I get to know a little more about this things
Replace 172.217.6.196 with your hosting IP and www.google.com to your domain.
You can find in cPanel (Maybe in right-hand side)
curl -I https://www.google.com --resolve www.google.com:172.217.6.196
Run this command in Command Prompt or Terminal. If this return some HTTP header response like
HTTP/2 200
content-type: text/html; charset=ISO-8859-1
p3p: CP="This is not a P3P policy! See g.co/p3phelp for more info."
date: Tue, 23 Feb 2021 05:59:00 GMT
server: gws
x-xss-protection: 0
Then you probably have ssl cert else not.
You shall consider Full Strict which is highly recommended for the end-to-end encryption.
Go to Cloudflare > SSL/TLS menu
There are 5 options in Cloudflare. In most cases, Cloudflare does smart selection as per detection.
off - You never need to set
flexible - This is not recommended. It connects origin over HTTP and return over HTTPS.
Full - Self-Signed or Valid, both will work. (This is a good starting point when you’re new to Cloudflare). One don’t need to pay for SSL certificate. In case you don’t have SSL, you can generate secure cert from here. Absolutely, free. (It will work as long CF is active).
Full Strict - This is a recommended selection. This will work if you have valid certificate from a trusted Cert authority such as Comodo, Let’s Encrypt. Also, this works with CF Origin Server certification that I mentioned in previous point.
Strict only (visible only for Enterprise customers as I heard) - requires valid cert.
Alright…I’m so embarrassed to do this publicly but I think there’s no other way in here. So …lets begin from the start… Please don’t judge me: I don’t use cPanel… I google it and I found it has prices… Is it absolutely necessary?
You do not need to use cPanel. That was just an example, an experience what I had once.
If you want to use Cloudflare, just make sure few things first
so I did this:
curl -I https://www.google.com --resolve www.google.com:172.217.6.196
and got this (among other things):
The only difference I can see from your is this HTTP/2 200 != HTTP/1.1 200 OK
I’m editing this with the hope I can still contact you, I wrote a new thread in https://community.cloudflare.com/t/hiii-user-user3996-i-cant-reply-anymore/246863?u=kayni
I said this:
Since I’m a new user this site doesn’t allow me to give more replies… It says I’ve reached the limit for new users.
I wanted to at least thank you, since I think this is going to be my last message in 21 hrs at least. And to tell you a few things:
" 1. Before updating nameservers, ensure all DNS records exist at Cloudflare. Else, you may face ‘DNS_PROBE_FINISHED_NXDOMAIN’ which means DNS couldn’t be resolved for your domain."
I think that’s exactly how my problems started!!! That was my first problem, everything else have been a growing snowball.
Other:
" In above cURL command, you need to replace 
www.google.com to your own domainHave you followed this way?"
Yes, I did as you said: I replaced 172.217.6.196 with my Hosting IP
Is there a way I can send you a message? I think this is going to be my last one in the forum:
I hope you get my message

I think I’m not allowed to send any messages 
Thank you very much @user3996 , I’ll do it as soon as I’m allowed or find out how to do it
