Node warning while tailing

HI.
Since yesterday I have been showing the following messagge while trying to tail my node.

WARNING:util: Got call_jsonrpc_api request error: result is None – is the ‘http://counterparty:4000/api/’ endpoint operational? – Waiting 3 seconds before trying again…

Any of what went wrong.

Thanks

This simply means that indexd is unavailable for some reason. Perhaps try restarting indexd via fednode restart indexd
