Claude MCP Connector stopped working

My MCP connection with Claude was working, but stopped last Friday. I removed and re-added the connection. I can progress to the to the Ring Central login and the get the following message. Your account was authorized, but no MCP server was found at the provided URL, or your account doesn’t have access to it. Check the server URL or your access, then try again. If this persists, share this reference with support: “ofid_df656a5d5597d7d5”. Any recommendation to fix this? I am using the https://mcp.labs.ringcentral.com/ringex/admin server URL
