I've added all the EU region IP addresses to my loadbalancer for allowed source IPs. But it cannot connect to my Vectorstore. If I remove IP restriction on my LB it works flawlessly. It worked with the IP restrictions until a week or little more ago.

Were there any changes of the NAT IPs?

LangSmith doesn't connect to vectorsores - are you referring to LangGraph Platform?

Sorry my bad. Yes I'm reffering to the Langgraph Platform. Specifically to this section of the documentation

You'll need to whitelist the IPs from the LangGraph Platform docs: https://langchain-ai.github.io/langgraph/cloud/deployment/cloud/#whitelisting-ip-addresses
