Hi, i hope that anyone can help me with this error, i have been installed aapanel ver 6.8.25 the last year, and everything was working well, but some months ago we have update to version 6.8.27 (this version fixed the ssl issue that we have in previous version 6.8.25), anyway, the thing is, when i try to add a domain in mail server, it gives me the error in subject, (see attached image), the ping command and also the nslookup command returned the correct ip from server (an A record was previously created in our DNS provider, with a mail.domain.com A record too, both pointing to the same ip of the server) , i tried to restart the panel (as i saw in other topic that with restart the panel the issue get solved), wait if there's a dns relay in propagation, but nothing, the error is still present, and i don't know why is happening this, i have already set eight domains in mail server with no issue before (note: those where created in version 6.8.25, the one i tried to create in this version 6.8.27 gives me the error), is the error relate to the version 6.8.27 maybe?? , i hope that anyone can help me with some solution or fix....thanks!!!

Hello, whether the A record of the domain points to the IP of the server, it cannot be a proxy The upgrade of the panel is only the panel will not upgrade the mail server plugin

aaPanel_Kern Thanks for reply, 🙂 but the record DNS is not with a proxy, is in godaddy, so i don't know why is not let me add a domain in mail server, is weird because as i said before, i added eight domains in mail server without a problem, first time i seen this errror message... 🙁

aaP_jpd Is the IP of the server the IP of the A record?

Add Domain in mail server result in A record parsing failed....

Hi, can you give us your aapanel information? The server makes a snapshot backup first, if possible, please send it to kern@aapanel.com.
It is recommended to fill in the following
Post link:
SSH IP address, account password and port:
aapanel login link address and account password:

No post link will not be able to know which user's information is, and the problem will not be processed

aaPanel_Kern

where i can get the snapshot backup? any location?

aaPanel_Kern

Take a snapshot of the website at the server provider.

aaP_jpd

sorry but i can not send you the info that you request 🙁 , talked to my supervisor and for security reason he declined to do that, is there any other option to check or any way to fix it?, is weird that doesn't work now, being that it worked before....thanks in advance!

Hi again,testing some things and checking others, i had encountered an error after press this buton:

this error gives me:

Can this be causing the error "A record parsing failed" or has something relate to it?

Thanks in advance!

PD: This error, as well as the error about parsing failed, it started to happen after we upgrade the version 6.8.25 to 6.8.27, before that no error in refresh the domain list in mail server and it can be added domain to the mail server without a problem, the real thing is with this version 6.8.27 we were unable to create new mail server domains for new clients....beacuse those errors. so please, can you help with those errors?....thanks!

Use this website to check if the A record, mx record used by the domain name mail server points to the IP of the server
https://dnschecker.org/all-dns-records-of-domain.php

aaP_jpd

thanks for reply, i already used that site, and the domain name mail server answered with the ip of the server correctly, what about those error that i mentiones when i press the "refresh domain record" in mail server??...that error wasn't happen before in version 6.8.25....thanks!!

aaPanel_Kern

Do all domain names point to the server IP? What is your mail server version?

aaP_jpd

yes the domain name and the mail domain name point to the ip's server, and the version of mail server is 4.6....thanks!

aaPanel_Kern

aaP_jpd
Send me all your domain names and server IP ?

aaP_jpd

Ok the domain names that arein mail server are:

but with this domain, the error appears:

The server ip is : 200.73.112.100

both domains (last image) have their respective A record in our dns provider, and both resolve correctly the ip server.

we tried to register that domain in another server mail in aapanel server that we have, and give the same error, both servers with aapanel in version 6.8.27

this server is behind a firewall...with NAT to public ip : 20xxxxxxxxxxxx0, as you can check, those domains : valore.cl and mail.valore.cl resolve the ip 200.73.112.100 that is the public ip of the server

aaPanel_Kern

aaP_jpd
It should be caused by the fact that the public IP does not exist in the network card of the server. Can you try to add a public IP to the network card after the server takes a snapshot backup?

aaP_jpd

i don't think that that was the issue, because before we were able to add eight domains in mail server with that configuration with no problem....that was in version 6.8.25, , but now in version 6.8.27 it can't be done and those two arrors appear from nowhere...

aaP_jpd

Hi, is me again, i have not yet tested put the public ip in the server's network card yet, but can i ask,
that what you said:

aaPanel_Kern Known issue: If the public IP does not exist in the ip a command will not be able to verify that the IP in the MX record is the same as the server IP

is a known issue in version 6.8.27 ? that wasn't present in version 6.8.25...thanks!

aaP_jpd

but is weird that error it happen now, because as i said before, we have no problem add domains to the server mail, it worked fine in version 6.8.25, it recognize well the A record, the MX records, as you can see in the image of domains, was several domains that were createdwith no issue, and with that public ip poniting to that server trought NAT....i don't know why is not working now....the only difference is the version of aapanel...worked fine in 6.8.25 and stop woking in 6.8.27, maybe something was broken in this version????....and add a public ip lto the server will eft the server open to everything, tha's a security risk, because of that, the server remains behind a firewall, as i said before, working fine in the previous version.....any workaround to solve the errors shown before??? ....both aapanel servers that we have that give mail service with server mail were not able to create new domains in the mail server in the last version...i don't know why

aaPanel_Kern

Check whether the export IP of the server is consistent with the public IP?
There is no risk in adding a public IP, because this IP will not directly reach your server, it is the IP of the firewall
Updating the panel will only affect the panel, and the mail server and the panel are independent of each other.
