F5 load balancer with 2 IIS server - First login always Invalid post request

PHPMaker v2024.4

I setup 2 IIS servers running my PHPMaker project and have F5 load balancer to route to either of the servers.

I set my project login page on my Microsoft Edge startup page. Every time I launch Edge, it will go to my login page but it will always show the below error when I login. I need to resubmit the URL again from the address bar so the page will refresh before I can login without error. I can consistently simulate this error.

400 
Bad Request
Invalid post request

Any idea why this happen? I don't want to disable "check token for form post".

You may enable Debug and also check HTTP response to see the error in more details.
