I'm worried because the email server was working normally. However, when I went to install a new domain on it, it broke.
Can't add domain on mail server

It means that there is a problem with the resolution of the newly added domain name. Check whether the relevant record points to the ip of the server. The proxy cannot be used.
I reinstalled all records and also reinstalled the mail server, but the problem persists. Any other ideas?
Please, can anyone help me?

Hi, can you send this file to my email? kern@aapanel.com
/www/server/panel/plugin/mail_sys/session.json
There is no such file in the folder

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
I can't, it's not a server for personal use. Please can I receive support without providing login credentials?

Reinstalling can't solve it, this needs to be checked by the developer.
please do we have any solution? something i can do? I can not give access to the server. I can harm myself.. 
How do I uninstall it completely without leaving any traces on the email server? So I can reinstall in a pure way.

After uninstalling the mail server, move the /www/vmail directory: mv /www/vmail /www/vmail_bak

Solved by installing aapanel on "centos 7" and "negix" ... using "Ubuntu" can cause this problem
