Freeze / Stuck when someone login

[Rui]

Hi I want to set up the Confluence and Jira SD behind Apache server (single server) using mod_proxy module

My server configuration is as follows:

my.company.com (HTTP)

    Apache 2.4.37 on Windows Server 2019

        - Confluence (localhost:8090 = my.company.com) (v6.13)

        - Jira Service Desk (localhost:8080 = my.company.com/track ) (v7.13)

Problem:
  When someone(not particular user) login (or websudo)  to Confluence server, the screen stucks and cannot login.  

What I know:

 - Confluence uses Jira user directory
 - Configured server.xml and httpd.conf
 - I can access to both instances remotely
 - Jira does not have such a problem
 - Even an user stuck on login screen, other users can use other Confluence features
 - When I undo <Connector> section at Confluence server.xml to original, the problem is solved.
    - This indicates Connector might be a problem
- Undoing httpd.conf (= not using mod_proxy) will not fix the problem

Would you help me to fix this problem?

Hi I know this is from two years ago but did you ever find a solution for this.
