Session has expired multi Mattermost server

Hello,
I deployed 2 servers mattermost (version https://releases.mattermost.com/5.39.0/mattermost-5.39.0-linux-amd64.tar.gz) on 2 servers local, with IP addresses are 192.168.0.2 and 192.168.0.3 behind the firewall.
[client] ----->173.16.1.1:8065 (NAT Port TCP 8065 to 8065) -------> 192.168.0.2:8065
[client] ----->173.16.1.1:8064 (NAT Port TCP 8064 to 8064) -------> 192.168.0.3:8064
Mattermost in server 192.168.0.3, I changed listen port in config.json is 8064, and check it is ready to listen on this port.
But: When I login in mattermost version desktop window (4.7.2) or chrome, if I login two servers same time, user auto logout and warning occur: Your session has expired. Please log in again.
Could you please give me some advice?

Hi there @sunq

Would you mind sharing a sanitized copy of your mattermost.log during when the Your session has expired issue occurred and also some context from the firewall log as well to see are there any blocking there so we can have more information what is happening within Mattermost and also your Firewall?

Hi Abdullah.alhabshi,
Many thanks for your response. I configured log mattermost mode DEBUG. And I found some log in file at server port 8064 when session timeout occurs follow my attachment.
My test case with mattermost desktop:

  • I log in to server port 8064, it OK
  • After that, I log in to port 8065 ==> user port 8064 occur “Your session has expired. Please log in again.” and mattermost.log changed.

I tested log in user with server port 8065 with mattermost desktop and user with server port 8064 with chrome. The result: 2 user login OK and I can send message with no problem.
Could you please give me some advice?
