"Failed to query node status... error in json rpc client, with http response metadata"

Error says it all: Juno returns HTML instead of JSON. Always getting this error with Juno. Anyone knows how to fix this?

hey @taitruong, this is usually a sign that there is some issue with the underlying node where it is failing to respond with the correct json formatted data. it could be due to rate limiting, fire wall settings, the node being offline, etc.

if you check the chain-registry and try to access the /status endpoint you will see that many of the publicly available nodes respond without issue e.g. https://rpc-juno.whispernode.com/status
