Trouble Updating LibreChat - NGINX "502 Bad Gateway"

[BennyMorton28]

I ran these commands (in picture attached) to update LibreChat to test the new Assistants update, and now when I compose up I can't get my webpage to display (the error screen I get is also attached). Usually I get this screen when I compose down and back up when I make edits and after 30s it refreshes, but now it's been a while and it's not loading still. I have my site hosted on digital ocean and did these update commands in the Ubuntu console, where I usually make all my edits. Does anyone have an idea what I did wrong/did I update in the wrong way? This is my first time running the LibreChat Ubuntu update lines of code too.

What kind of edits? If you made code or NGINX config edits, you should not be updating with those instructions.

Did you make a separate branch for your edits? Either way, you might have some conflicts when merging the latest changes, which is what git pull would do. If you made NGINX edits, you likely have a conflict in the config file now.

See these docs on correctly editing NGINX and updating after doing so:

In any case, you should check your container logs.

To check active docker container instances
docker ps

Then you can check individual containers like this, using the "name" from docker ps output
docker logs LibreChat-NGINX

I only really make changes to .env, librechat.yaml, and then the override file. How should I go about updating Librechat if those commands aren't the right ones?

Generally those would be right for you, but you're using NGINX. It depends on what's going on, please look into those logs.

Alternatively, you can ditch NGINX and use Traefik instead, which doesn't involve git changes and may be easier to maintain:
