Jeager UI does not list the Operations because of a timeout

[BlackDex]

Hello there,

I have a small question regarding the Jaeger UI/Query.
When I Select a service it normally loads the Operations.

But currently it seems the Operations query ends in a Gateway Timeout.
Is there some way to solve this, or limit this somehow?

I'm using ElasticSearch and it has a jaeger-service-read, and there is one for an dev environment and one for prd.
The prd fails, the dev does not.
The dev index is 3.3GB in total size, while prd is 121.3GB.

Are there any settings i can change to get this working again?

Thanks in advance!
