Need Help on connection refuse error when query top odatav4 endpoint

(0) ShareShare

Posted on by 82
Hi Experts,
 
We query the top endpoint of ODataV4 to get all the endpoints exposed under the tenant.
such as
GET https:/api.businesscentral.dynamics.com/v2.0/_tenant_id_/Production/ODataV4.
RESP
{
/@odata.context/: /https:/api.businesscentral.dynamics.com/v2.0/_tenant_id_/Production/ODataV4/$metadata/,
/value/: [
{
/name/: /Company/,
/kind/: /EntitySet/,
/url/: /Company/
},
{
/name/: /AccountantPortalActivityCues/,
/kind/: /EntitySet/,
/url/: /AccountantPortalActivityCues/
}
......
 
But recently, we started to get the connection refused error at around 4:00 am UTC,
then the same error stuck on this query in the next 1 or 2 hours during the retrying,
and then after about 2 hours the error went away, and everything back normal.
 
We were wondering if any other partners were encountering the same problem recently.
Or is there could be a BC server recycle or something scheduled at that timeframe can block inbound request?
Also, we are curious of that if the top endpoint of ODataV4 (https:/api.businesscentral.dynamics.com/v2.0/_tenant_id_/Production/ODataV4) is not designed for data query purpose.
 
Thanks!
