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

@mmtrade said in Trouble with IPv6 (was "HELP NEEDED URGENTLY") !!!:

lastly i want to understand why yahoo is boncing mails from this. I try to send emails to yahoo and i get a failure delivery. What should I do?

What does the email status say - https://docs.cloudron.io/email/#server-status ? Maybe outbound port 25 is not working. If that's the case, you have to use a relay to send email - https://docs.cloudron.io/email/#relay-outbound-mails .

@necrevistonnezr holy heck! What a bizarre snap directed at you. Probably everyone reading this exchange had the exact same thought as you... I did. I suppose if there is a Paid Support Level which allows one direct access to the admin/developers the OP's question could be understandable... but with their manners it would HAVE to be a very high amount.

@mmtrade It is customary and welcome when users share what solutions helped them. Care to share what rectified all those issues?

@mmtrade

Yahoo rejects your emails due to fresh domain registration.
Some popular email blockers from 1 to 6 months depending on the domain tld. A good solution to this problem is to send from yahoo email, icloud, gmail etc to your own email.
Send a normal long text message once a day and you can't send in bulk to start with from your mail because then they will permamently block your IP address.
At my place with a .cloud domain, I had a problem receiving iCloud emails for six months.

On top of that, Contabo IP addresses are popular among e-mail providers as spam servers.

@matix131997 It does not deliver eitherway

I have tried to send from yahoo and it keeps bouncing back

@girish please share your ideas on this solution.

@mmtrade this is a yahoo issue
try contacting them about it

I’ll save you the trouble.. use an smtp relay like mailgun

[girish]

@mmtrade usually the IP addresses in most VPS providers are blocked by the big mail providers. You have to use a mail relay or be patient with warming up the IP for say 6 months or so (and contact the big providers to unblock your IP). There is no other solution to this.

@girish I

I have the same problem since today. I can't install any app anymore, I get the "ipv6.api.cloudron.io unreachable" error.

ubuntu@s3:~$ curl https://ipv6.api.cloudron.io/api/v1/helper/public_ip
curl: (28) Failed to connect to ipv6.api.cloudron.io port 443 after 132362 ms: Connection timed out

A problem with your server? It doesn't answer to ping.

ubuntu@s3:~$ ping ipv6.api.cloudron.io
PING ipv6.api.cloudron.io(2604:a880:800:10::b66:f001) 56 data bytes
^C
--- ipv6.api.cloudron.io ping statistics ---

Thanks in advance for your help.

@csteiger the server is definitely up

$ ping ipv6.api.cloudron.io

Can you check your network? Are you able to ping other IPv6 addresses?

@girish

Thanks.

I don't know what happened, the local DNS was down... a reboot did it

[mmtrade]

@girish my cludron server is offline..

i do not know why but no matter what i do and retsart it is still offline

[mmtrade]

[nebulon]

Is the DNS resolving to the correct IP? At least the one it resolves for me is not even pingable, so is that server publicly reachable?

[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

[mmtrade]

https://mxtoolbox.com/supertool3?abt_id=AB-631A&abt_var=Variation&action=a:ronsteels.com:all

[mmtrade]

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.

[nebulon]

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.
