HTTP/1.1 500 Internal Server Error

Hi,

i’ve set up my django app with postgres, gunicorn and nginx, and it was working perfectly for more than a month, yesterday and when i tried to access the website, it gaves me Internal Server Error while i didn’t change anything, so i checked the nginx logs and here are the results :

2023/01/27 14:09:15 [crit] 1094411#1094411: *3723 SSL_do_handshake() failed (SSL: error:0A00006C:SSL routines::bad key share) while SSL handshaking, client: 162.243.141.20, server: 0.0.0.0:443
2023/01/27 16:30:17 [alert] 1124567#1124567: *8 open socket #3 left in connection 4
2023/01/27 16:30:17 [alert] 1124567#1124567: *9 open socket #12 left in connection 5
2023/01/27 16:30:17 [alert] 1124567#1124567: aborting

and i’m not sure if the SSL has something to do with it since i had that error before, but one thing that i actually noticed is that when i checked the status of apache2.service, it says Failed to start The Apache HTTP Server., but i think it’s normal since i’m using nginx right ?, here is what i get :

**×** apache2.service - The Apache HTTP Server

Nov 26 17:00:32 ubuntu-s-1vcpu-1gb-fra1-01 systemd[1]: **Failed to start The Apache HTTP Server.**

So i tried to check the error logs of apache2 using :

sudo tail -n 2 /var/log/apache2/error.log

but it returns nothing,

btw : nginx and gunicorn status are all active and everything looks good, i tried to restart them but i still get the error.

so can someone please help me with this and let me know what should i do ? i’m a beginner into this and just started learning. thanks and i really appreciate your help.
