Ztree The host cannot access the case analysis under the CMDB

One day find the host list of the CMDB home page click Error 502
Fault:

Error troubleshooting steps:
1. First check if there is a problem by manual command (there is a port number in the URL, here I manually start the CMDB service no problem)

2. Open nginx error log deubg mode

View logs (connection denied)

3. View Uwsgi logs (problems found)
   
   Problem found:
   The URL address is longer than 4,096 characters, and 4096 is the default value of Buffer-size in the Uwsgi configuration, so you only need to change the buffer-size to a larger one.
   4 Add configuration Restart Uwsgi Service
   
   Restart Service
   [Email protected] cmdb]# systemctl restart Uwsgi
   The end result: problem solving
