centos7.6 Unable to display login page

## Steps to reproduce
1. I have carried out the installation steps correctly
2. I run the following command to start the server and it doesn't seem to be a problem
```
[root@node190 bin]# ./hawk start
[12841] Puma starting in cluster mode...
[12841] * Version 4.3.5 (ruby 2.5.5-p157), codename: Mysterious Traveller
[12841] * Min threads: 0, max threads: 1
[12841] * Environment: development
[12841] * Process workers: 1
[12841] * Preloading application
[12841] * Listening on unix:///usr/share/hawk/tmp/hawk.sock
[12841] ! WARNING: Detected 1 Thread(s) started in app boot:
[12841] ! # - /opt/rh/rh-ruby25/root/usr/share/gems/gems/concurrent-ruby-1.1.6/lib/concurrent-ruby/concurrent/atomic/ruby_thread_local_var.rb:40:in `pop'
[12841] Use Ctrl-C to stop
[12841] - Worker 0 (pid: 12876) booted, phase: 0
```

3. But when I visit the web : https://:7630,Nothing

4. I made an error while testing the hawkapi-server project,It seems that there is no route. I need to write swagger.json?
```
[root@node190 bin]# curl --insecure -u hacluster:password https://:7630/api/v1/cib
[api/v1]: No route for /api/v1/cib
```
