Error retrieving tool list from MCP server: 'HH'. Http status code: 424 (Failed Dependency)

I’m currently experiencing a weird error where after I add an MCP server to my chat and perform a unit test (send through an input on the “chat with your prompt” on the right hand side - it returns the necessary. However - when I call the chat via api - it is returning Error retrieving tool list from MCP server: ‘HH’. Http status code: 424 (Failed Dependency) Then when I try again with a unit test - it returns Error retrieving tool list from MCP server: ‘HH’. Http status code: 424 (Failed Dependency) I then remove the MCP from tools and re-add it back in and the unit test works again but i then loop into the same error when trying to run it from api again.
