https://api-fxpractice.oanda.com/v3/accounts/<account_id> is not redirected by Oanda. It seems Zorro needs to query the specified account, not all accounts.

We confirm this problem. Apparently there's some issue since some days with the Oanda REST API. With curl it doesn't work either. We're in contact with them and will post here when we got new information.

The reason of the problem is that a certain API command, for reading the account list, does not work anymore since last week. This does not affect running sessions, but it affects login to Oanda.

We've uploaded a modified Oanda plugin that does not use this command. You can download it here: http://opserver.de/down/Oanda.zip.

You can login with this plugin, but must now enter your account ID in the User field. Leaving the field open does not work anymore.

I hope that Oanda fixes the problem soon.

Thank you jcl. I can confirm this dll solves this problem. Much appreciated.

It does work with curl. HTTP redirects need to be followed. curl -L

curl -v -H "Content-Type: application/json" -H "Authorization: Bearer DummyAPIKey" "https://api-fxpractice.oanda.com/v3/accounts"
Using HTTP2, server supports multi-use
* Connection state changed (HTTP/2 confirmed)
* Copying HTTP/2 data in stream buffer to connection buffer after upgrade: len=0
* Using Stream ID: 1 (easy handle 0x55746ec5d800)
GET /v3/accounts HTTP/2
Host: api-fxpractice.oanda.com
user-agent: curl/7.68.0
accept: /
content-type: application/json
curl -v -H "Content-Type: application/json" -H "Authorization: Bearer DummyAPIKey" ""https://api-fxpractice.oanda.com/v3/users/@/accounts"
{"accounts":[{"id":"101-001-FAKENUMBER-001","tags":[]}]}
curl -L -H "Content-Type: application/json" -H "Authorization: Bearer DummyAPIKey" "https://api-fxpractice.oanda.com/v3/accounts"
{"accounts":[{"id":"101-001-FAKENUMBER-001","tags":[]}]}

FYI: if someone needs to hear this for me the connections to Oanda demo accounts works now

We have implemented a redirection in the latest Zorro version. It should have solved that problem.
