Security error certificate issue

[brujo]

Hi
I am receiving the following error on my browser when I attempt to go to my AS6704T NAS:
"Security Error" "go back" "proceed anyway"
If I select "proceed anyway", I see the following message:

"Your connection is not secure
xxxxxx.myasustor.com" certificate name does not match input.
You should not enter any sensitive information on this site because it could be stolen by attackers.
Certificate Details"

Diging down, I see a page that describes an error with the "let's script" certificate:
"Issued To
COMMON NAME (CN)
xxxxxxx..myasustor.com
Issued By
COMMON NAME (CN)
R3
ORGANIZATION (0)
Let's Encrypt
COUNTRY (C)

How can I fix this issue?
I just know the network basics
Thank You

Firstly, please edit and redact your DDNS name, else everyone will be able to reach your NAS.

Secondly the way you access the domain should match the CN (or one of the SANs if applicable). E.g. your DDNS is 1234.myasustor.com, then you'll need to access as https://1234.myasustor.com:8001.

Hi Nazar78
Thank you for your reply
Do you mean the "Server Name" on ""Network" "Settings"?
Do I need to rename the "Cloud ID"?
Thank You

No I mean edit your original post to remove your domain name because anyone can try to connect to it.

What URL did you use to access your NAS that you got that error? Did you access using IP? E.g. https://192.168.1.x:8000? If that's the case then it's perfectly normal to see that error.

If that's not the case then try give more details, screenshots might help.

Thank you for your help, I appreciate it.

No problem but you still left your domain seen in the second paragraph.

Hi Nazar78
I imported a certificate and I am not able to remove it, I am able to edit or set it as default but not remove it.
Is there another way to remove it from the list.(See attached screen shot)

I tried to create a lest script, however, it says I reached the limit.
Do I have to wait a week to try again?

Again, I really appreciate all your help.
Thank You

Yes you'll have to wait or use another email/DDNS. To remove a cert, you need to set another cert as default, set the cert that comes with ADM as default then you can remove the previous cert.

PS: I don't see your screenshot. Edited: also of course you can't remove the cert issued by Asustor.

Hi Nazar78
The DDNS should point to my public IP?
I was able to create the let's Script, however, I still get the "An SSL error has occurred and a secure connection to the server cannot be made"

When I type my public IP with xxx.xxx.xxx:xxx80 I get the following:
"Congratulations! You have successfully enabled the Web server on your ASUSTOR NAS".
Shouldn't I be getting a secure connection?
Where else should I be looking?
As always, my thanks for all your help.

Yes.

HTTPS is default port 443. Think you need to show some screenshots.
