OSError: [Errno 98] Address already in use: ('0.0.0.0', 7800)

Can you please help me?

aaPanel_Kern

Hello, is the problem solved?
Is it possible to solve the problem by stopping aapanel and then updating to the latest version?
bt stop && bt 16

aaP_fasuku

I tried what you suggested but unfortunately, the issue continues. I do not have access to the aapanel. The login screen does not load. What else can I do?

aaPanel_Kern

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:
Detailed problem description:

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

aaP_fasuku

I cannot give you access to my ssh because is setup with certificate and I cannot create a user to access it with a password. Can you give me some incrustations that I can follow and post the results back to you?

aaPanel_Kern

Hello, what error message does the log show?
Check what program is using port 7800. Is it possible to solve the problem by trying to force close it?
netstat -tulnp|grep 7800

You can also use this command to test whether it is normal
/www/server/panel/script/webserver-ctl.sh stop && bt restart

aaP_fasuku

netstat -tulnp|grep 7800
tcp 0 0 0.0.0.0:7800 0.0.0.0:* LISTEN 32538/nginx: master

aaPanel_Kern

aaP_fasuku
Hello, check the directory of this process, if it shows /www/server/panel/webserver/sbin/webserver
Is it possible to force close this process and restart it?
ps aux|grep 32538
kill -9 32538
bt restart

jonhcarter

Is the port open in the panel firewall? VPS provider firewall, too? Have you changed the port recently?

aaP_fasuku

jonhcarter Thank you for your answer. The Port i open in the VPS and the panel. The issue occurred after updating ubuntu and restarting the server. It was working for years without any issue.

jonhcarter

Have you not made vps snapshot or backup before the update?

if not you can try this : https://nethostingtalk.com/threads/2301/
