Good afternoon. Help please. I install Aapanel on a clean server. The terminal does not open. Writes a connection error. Connection lost. What could be the problem? Tried reinstalling twice doesn't help.

sales_bbooom Hi,Use the ssh tool or terminal to log in as the root user to execute commands btpip install simple-websocket==0.10.0 && bt 1

Thank you very much. Everything worked. This error has not been encountered before. For some reason it now appears during installation. Thanks for helping out.

Some personal information has been hidden

aaPanel_Kern Another unknown problem appeared to me. She hadn't met before. I'm trying to send a test email to my email. Writes that it is impossible to send. What's wrong with him...? Everything used to be fine.

Is it normal to try to send again? Check Service Status Is the service running? sales_bbooom

aaPanel_Kern As far as I can tell. The services are working. I tried to send 5 more times to change the text. Even reinstall the entire system again. Nothing helped. This error started appearing the other day. Literally 4 days ago. Before that, all copies of Aapanel worked properly and are still working.

sales_bbooom 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 An email with access has been sent to kern@aapanel.com

sales_bbooom Hi, try to create a new user. I newly added user test is normal kerntest

aaPanel_Kern Tell me, and in which section it needs to be done. I can't find where to create a user.

The terminal is not working

At the same time, check the postfix configuration, which can be viewed in the server status
"mail.135mailtest.com" is replaced with your domain name
Put:
smtpd_tls_chain_files=/etc/ssl/private/ssl-cert-snakeoil.key,/etc/ssl/certs/ssl-cert-snakeoil.pem
Change to:
smtpd_tls_chain_files = /www/server/panel/plugin/mail_sys/cert/135mailtest.com/privkey.pem,/www/server/panel/plugin/mail_sys/cert/135mailtest.com/fullchain.pem
Note to replace 135mailtest.com with your domain name.
Also check /www/server/panel/plugin/mail_sys/cert/135mailtest.com/ for privkey.pem and fullchain.pem files

You can use this command to check whether the correct SSL is configured
openssl s_client -connect mail.135mailtest.com:587 -starttls smtp
or
openssl s_client -connect mail.135mailtest.com:465 -starttls smtp

If the display is not OK, please re-apply for SSL

I checked
/www/server/panel/plugin/mail_sys/cert/135mailtest.com/

I found the files privkey.pem and fullchain.pem

I tried to enter commands into the terminal

At the same time, I have SSL installed. I attach a screenshot of the confirmation

I didn't understand what I need to do in your first assignment. What do I need to replace in these files?

postfix config in service status

sales_bbooom

aaPanel_Kern

I went to postfix config in service status.
Found a line

smtpd_tls_chain_files = /www/server/panel/plugin/mail_sys/cert/135mailtest.com/privkey.pem,/www/server/panel/plugin/mail_sys/cert/135mailtest.com/fullchain.pem

Replaced by

smtpd_tls_chain_files=/etc/ssl/private/ssl-cert-snakeoil.key,/etc/ssl/certs/ssl-cert-snakeoil.pem

Restarted postfix
I tried to send a message. Writes an error again.

Can you help fix the problem? I can't do it on my own

I returned this line back as it was originally written for me.

smtpd_tls_chain_files = /www/server/panel/plugin/mail_sys/cert/play-4-game.ru/privkey.pem,/www/server/panel/plugin/mail_sys/cert/play-4-game.ru/fullchain.pem

I saved it. But it didn't help. An error occurs when sending

Failed to send mail, error reason [[Errno 111] Connection refused]-

It is recommended to paste the relevant logs, and check whether the export port 25 of your server can be connected?
telnet smtp.google.com 25
