aaPanel Refuses connection on highload service stack

aspc_kz

aaPanel is awesome solution for non-commerce hosting, but if there 30 hosts in website tab (even static reverse proxy), aaPanel doing some strange things - it makes ERR_CONNECTION_RESET that broke some scripts, like SSL renew.

Is there any solutions for this?

Hello, using a reverse proxy, please use the dns method to verify.

aaPanel_Kern Any Method fails(stuck because CONN_RESET).
aaPanel automatically disables reverse proxy feature on website while getting SSL.

When i'm moving in aaPanel's interface fast (but sites registered one or two), it refuses connection sometimes. I've think it because WAF feature enabled, but it keep doing thing without WAF. And now, when i have 30 websites registered, aaPanel stucks randomly. I think it because flask gevent WSGI dies on heavy requests.

It is recommended to check whether the server status is normal?

aaPanel_Kern

aspc_kz
Hello, can you tell us in detail how you do it?

aspc_kz

aaPanel_Kern technically, i don't know how. full system fix (reinstalling panel) don't help. maybe there are some logging in aaPanel? if it is, I can provide some system logs

aspc_kz
Hello, are you using the api to build multiple sites within 1 minute?
Check the panel log bt 22, can you enable the developer mode to see the error?

aspc_kz

aaPanel_Kern I don't use api, i can enable developer mode in aaPanel settings, bt 22 don't show any crashes.

Also just got this error

aspc_kz
Hello, what is your panel version? Are you using nginx? Have you tried repairing the panel with the command: bt 16

aspc_kz

aaPanel_Kern Panel version was latest stable (6.8.26), now updated it to beta (6.9.68) because bt 16 hasn't any affect on panel. just did bt 16 now and it downgrades to stable version. Now panel restarts (Refuses connection) many times often than before, even without any tasks

it hangs on this state

aaPanel_Kern

aspc_kz

Looks like recursive stack overflow.

In our department we have more than five system administrators that can keep aaPanel webpage open for days. Maybe very long session triggers this error.

aspc_kz

I comment out 4190 line in class/public.py
#if not session.get('login',None): return error_not_login()
And it solved my problem!

Hi, have you turned off SSL for your panel? Or have other colleagues turned off SSL?

aspc_kz

aaPanel_Kern SSL for panel is turned on.
