API stopped working after update

Good afternoon. The day before yesterday, we upgraded to a new version on our server (there was OneBox, it became OneBox OS), and after that the API stopped working. All links return a 404 error. Below is an example of an API request that used to work but now returns a 404 error: Can you please suggest what could be the issue and how to fix it? Perhaps you need to write something in the .vhost file? Here, just in case, is our .vhost file: root@cromleh /etc/nginx/sites-enabled # cat cromleh.crm-onebox.com.vhost server { # listen *:80 default_server; # if need default website listen *:443 ssl; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_certificate /etc/letsencrypt/live/cromleh.crm-onebox.com/fullchain.pem; # managed by Certbot ssl_certificate_key /etc/letsencrypt/live/cromleh.crm-onebox.com/privkey.pem; # managed by Certbot server_name cromleh.crm-onebox.com www.cromleh.crm-onebox.com m.cromleh.crm-onebox.com www.m.cromleh.crm-onebox.com; root /var/www/cromlehcrmonebo/web1/web/; index inde
