connectivity problem: cannot get candle data

When I use v20-instrument-candles EUR_USD

I got following error message

v20.errors.V20Timeout: v20 REST request to https://api-fxpractice.oanda.com:443/v3/instruments/EUR_USD/candles has timed out (read)

And then I checked the official doc and tried another method to get candle (example from doc, excluded my own token & account)

curl \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer <AUTHENTICATION TOKEN>" \
  "https://api-fxtrade.oanda.com/v3/instruments/EUR_USD/candles?count=6&price=M&granularity=S5"

Still I got

{"errorMessage":"An internal server error has occurred."}

But I am able to create order using python src/market_order_full_example.py

So this seems to be a problem with connectivity of oanda’s candle api. Anyone knows how to fix this problem? Thanks in advance!

My personal experience is that both environments are very stable. Last week the live environment had issues during the day, over several days, that was also to find on the health page. I have ‘oanda-trading-environment’ installed on a raspberry pi and it has very long uptimes. This maintenance weekend was an exception to other maintenance weekends.

Just noticed there were issues again in live streaming …

Guess your are still waiting for it to come up…

OANDA had an extended maintenance program (was till yesterday on the login page). V20 history candle history is still not working on the practice env. Streaming quotes work fine though. The old V1 has no issues.

I just tried the V20 live-environment to perform the same request to get some candle data and that works fine too.

So if you only have practice you still need some patience …
