Azure Redis Cache Connection due to #6850

[peeeteeer]

What happened?

since 13th of April 2025 I have issues with Azure Redis Cache... see logs below... a deployment of April 9th is working perfectly fine. I do see quite a lot of changes in the redis area at this day. So I suppose something has changed...

Version Information

see text above

Steps to Reproduce

Create a LC instance connected to an Azure Redis Cache and wait for error message in log file... happens usually every 10 minutes...

What browsers are you seeing the problem on?

I don't have Azure Redis setup to test, PRs welcome

yes, this one... not sure when I will have time to look into it... but it happen with this PR I think

Moved this to troubleshooting since I can successfully use "Azure Cache for Redis"

Follow the guide for hostname and password, which you can then include in the URI like this:

REDIS_URI="rediss://:PASSWORD@HOSTNAME:6380"
# enables the service in LibreChat
USE_REDIS=true

You can also find credentials here:

initially it works for me as well - but if there is no traffic most hosted Redis Services terminate the connection after ~ 10 minutes... so what you need to do is to ping every 5 minutes or so... I got a fix ready and will open a PR today...

Great! I was not aware it would disconnect every 5 minutes, this is definitely not the experience with other Redis connections.
