Hello!

I have two instances of Odoo in a server in the cloud. If I make these steps I get "Internal Server Error":

1. I make login in the first instance

2. I close the session

3. I load the address of the second instance in the same browser

If I want to the second instance work I need to remove the browser cookies first.

On the other hand I have two instances in my local PC as well and I don't need to remove the cookies to make them work if I change from one to another.

It's not a NginX issue because I tried with and without it.

If I load them in differents browsers (Firefox and Chromium), they work well at the same time.

What could it be?

Thanks and greetings.
