Trouble with IPv6 (was "HELP NEEDED URGENTLY") !!!

[mmtrade]

@nebulon I checked in my cloudflare and i just readjusted the server DNS to the IP

It is still not working and i do not know why? what should I do from here?

[humptydumpty]

@mmtrade it could be because of DNS propagation, check it using an online tool: https://mxtoolbox.com/dnspropagation.aspx

and yes i adjusted the IP on my cloudflare. I initaially rebooted my VPS and i think that was why the DNS changed. But i had to go to my cloudflare to adjust this also

[mmtrade]

so i corrected the issue with the DNS now.

Is it working now? Is your dashboard domain resolving to the correct IP ? At least from here it appears to be resolving to an IP which is not reachable on any port I've tried.

[mmtrade]

it is not working... the domain is resolving to the correct IP but i cannot seem to open the cloudron at all

this is my vps IP 185.203.217.223

you can check from any tool to see if it is resolving fine. I think the problem is on cloudrun

can you advise

I checked that your domains have the IP address you provided and it detects correctly, that is, the DNS is set correctly. The next test I did was a port scan and BUM. They are filtered. If you didn't set something with SSH some settings then Contabo restricted IP access to the server e.g.: a large number of requests or an attack on your servers e.g. SSH hacking attempt.

If you didn't have a secured server with a few parameters that restricts the attack on SSH in sshd_config with a public key then you really had hack attacks.
I too have 2 servers in Contabo and I didn't experience any attack because I already set up according to the security standard SSH access to the server right after launching the Cloudron platform.

The solution? You need to write to support to unblock the IP address, if not then change the address to another one and manually enter in Cloudflare the new address in each entry "A" and "AAAA"

@matix131997 I really would need some help chaning it manually. I have written the support and still no answer. I could use your help if you come on a live followup

@mmtrade
Now on a quick note, I can't recall how it changed the IP address. You'll have to wait from tech support for them to fix the problem for you. If they unblock it for you, you need to secure the server well, i.e. limit SSH access.

@mmtrade
Okay, after a thorough analysis of my account. I have a VPS the cheapest, where I could not change the IP address. It remains technical support to solve this and as you in which you manage the server you have the task of securing the server.
