429 Error when raising a new connection for a File System connector

[onyx-lemur]

Describe the Bug with repro steps

1. Go to an existing workflow
2. Existing File System connectors will present 'invalid connection' errors
3. Trying to reselect the existing connection will take you to the 'create a new connection' page, despite 15 pre-existing connections
4. Re-entering the connection as a new connection (but same details) presents the 429 error

Full response:

Failed to create connection: {"error":{"code":"ConnectionGatewayFailure","message":"'The DMTS API call failed with a retryable response code.'. Status code: '429'. Error info: '{"code":"NotSpecified"}'."}}

We did get a 'requests are being throttled' message earlier in the day.

Just to add on - the 'Cancel' button also doesn't work on the new connection page when this happens (but clicking the top right X does exit out).

Any advice on this?

We are still suffering on this issue, and it has now spread to our production environment. We now are experiencing an issue with raising new connections that aren't appearing in the connections overview page (so are uneditable).
