Hi all we are encountering a strange issue between our Discourse environments.
We have 3 different Discourse test environments. Let’s call them:
- [A.domain.com](http://A.domain.com)
- [B.domain.com](http://B.domain.com)
- [C.domain.com](http://C.domain.com)
Environment:
- Hosted on AWS
- All 3 share the same redis server and same RDS postgres instance with separate DBs and separate EC2 instances
Problem encountered:
- I log into [A.domain.com](http://A.domain.com) and [B.domain.com](http://B.domain.com) as “administrator” in different Chrome windows
- I log out of [A.domain.com](http://A.domain.com)
- **[B.domain.com](http://B.domain.com) immediately shows that I’ve been logged out and to refresh!**
- After refreshing I’m still logged into [B.domain.com](http://B.domain.com), and logged out of [A.domain.com](http://A.domain.com)
- I’ve also tested with A & C, or B & C with same result
- We’ve also tested this on **different** devices with same result
We are very concerned something is sharing our configs, etc and will cause issues as we migrate to our production environment, or its just a weird browser notification thing.
Any thoughts on what may be causing this? 🤔
Thanks in advance!

Are you 100% sure that every site is connecting to a different redis instance?

They are all sharing the same redis instance. Are we required to have separate instances/servers?

Ok. I guess we misread on some AWS install documentation. Let us try that and we will get back to you.
