HTTPS Sender adapter in iFlow shows sometimes a 401 error

[RonSterren]

Hi

I have an iFlow with a HTTPS sender adapter. We created a specific role and assigned the role to this iFlow and a clientID (generated in BTP). In general everything is working fine. An external partner is calling the endpoint and sending messages (XML IDOCs).

However we now have a situation that a specific message (relatively large, size 1MB, XML IDOC) is not being processed by the HTTPS sender adapter.

When checking the Integration Suite Logs I see the following that a HTTP 401 is returned.

Also a successfull request is having 401s but will get a 200 in a next request and will continue.

How do I need to interpret this and how can this be solved?

Thanks

Ron
