Do you have any details of the 500 error from your logs?

Load Balancer Breaks SSO
I have 4 VPS setup as web servers and a load balancer through digital ocean. If I keep 1 server in the load balancer, SSO works fine. When I add a second or more servers, its stops working.
What I mean by it stops, is that it starts to give a 500 error but for whatever reason will randomly register or not register a new user.
The load balancer has sticky sessions enabled and all the web servers are identical. There is a separate VPS that is running the database that they all connect to and I dont have any issues with it working with the database.
I cant figure out why it wont work on the load balancer at all. I have a similar setup in my house using VMs and nginx doing the load balancing without issue.

I do have one. I dont quite understand it though.

I believe that is the right one, I pulled from logs folder in laravel. Since Nginx wasnt giving me anything.

After I did some more digging around. I found that my session and cookies where the cause.
config/session.php had 'domain' => env('SESSION_DOMAIN', null), and my .env doesnt have this defined. I added and set the domain as needed. Cleared my cookies, cache, ran php artisan cache:clear and composer dump-autoload
The login now works without issue.
