RingEX Admin MCP server returning "server_busy" on every call

I connected the RingEX Admin server (https://mcp.labs.ringcentral.com/ringex/admin) to Claude as a custom connector. OAuth completes successfully and the tools load, but every API call returns {"error": "server_busy"}.

Is there a known issue with this endpoint? Is there a status page I can check?

Account type: Admin. Region: US.

​@Jamie_Smith I’m checking in with the MCP support group. 
Give me some time to secure an answer.

Just replied on your other comment, but posting here in case someone click on your thread. 
The team is investigating the issue and working on a fix. 
I’ll post here with any updates!

We’re also having no luck with the RingCentral Admin MCP server. (https://mcp.labs.ringcentral.com/ringex/admin)

Been trying to get this to work since last week. We currently get 404 errors when trying to set it up as a custom connector, though at one point on Monday we did get a 503 error which leads me to believe at least the URL is correct.

​@CoreyMcMillan The truth is that the Admin Server is temporarily offline. We are working to restore it with a new set of tools in the coming days. If we made an alpha version available to you - with us having done less rigorous testing, would you be interested in helping us try it out?

​@ByrneReese Any ETA on getting that server up and running? and we are also happy to test that for you if that is something going to work as admin
