Resolved Impossible to connect with customized URL

Obsidian 18.0.51

Hi,

I got an instance with Amazon Lightsail (Ubuntu) running with Plesk.
My domain is managed through Amazon Route 53.
I changed the URL of plesk by plesk.mydomain.com
I created a record (A) in Route 53 to link subdomain plesk.mydomain.com with my IP address used by Plesk.
I installed let's encrypt ssl certificate to this subdomain plesk.mydomain.com
If I check DNS plesk.mydomain.com I can see that linked has been done correctly with DNS propagation checker.

I opened port 8443 in my Lightsail instance in any case.

Problem that I have now, is that I can't connect to my Plesk login page using https://plesk.mydomain.com, I'm getting a timeout issue.
If I try the link https://plesk.mydomain.com:8443 I'm getting error "ERR_ADDRESS_UNREACHABLE"

If I try to connect to Plesk with my IP address using 8443, it's not working anymore...
So to resume, I don't know how to retrieve my access to Plesk....

Could someone give me some help?

What happens when you try to address your server using the IP address instead of the domain name?

When I open SSH it's displaying something this:
* Plesk Control Panel: https://13.xx.xxx.99
So when I try to connect using this IP, the browsers are loading during 30 seconds and display ERR_CONNECTION_TIMED_OUT

When I run command sudo plesk login I'm having this result displaying my domain:

https://www.plesk.mydomain.com/login?secret=cSHxxxxxxxs9M

When I try https://www.plesk.mydomain.com, I'm getting this result:

DNS_PROBE_FINISHED_NXDOMAIN

But none of them redirect to plesk login page.

If I try to connect to Plesk with my IP address using 8443, it's not working anymore...

Try opening port 8880 and going to http://<IPAddress>:8880

Try opening port 8880 and going to http://<IPAddress>:8880

Unfortunately, same result...
Here are the ports open in my Lightsail instance

FYI I disabled the access domain which could be origin of the issue:
$ sudo plesk bin admin --disable-access-domain
SUCCESS: Plesk is now accessible only over the port 8443.

When I send the command to get the login URL, I'm getting this result:

$ sudo plesk login

https://13.xxx.xxx.99:8443/login?secret=f7G8xxxxxxxJgQV

But unfortunately still getting time out issue...

If you're getting timed out it sounds like a firewall is still blocking it. I usually don't recommend this but disable ufw if you have it enabled and triple check your aws security to allow 8880 and 8443 to your server. If you're able to connect after disabling ufw and after confirming 8880/8443 is set for allow then we basically confirmed that ufw was blocking it.

@scsa20 Don't know how he did but one guy of my dev team resolved this issue...
