We are in the process of migrating AS2 Connections from onPrem TN to wm.io B2B.
Apart from a lot of other issues we currently face this one which we need to solve quickly.
When a Partner (TRANSPOREON) sends a message to us the first message works basically.
Any further message sent results in 401 - „Invalid or expired session identifier“.
We found several very old reports of this error in webMethods Forum and KB - but no real solution actually.
Anyway - in the case of wm.io we do not see any change of changing http configuration using some params or something like that. (e.g. set watt.security.session.forceReauthOnExpiration=false - which might help)
Do we have a chance to see low level http wire data somewhere - to check http headers or things like that in wm.io?
If our partner needs to change configuration we would need to know what his http client does wrongly.
many thanks for your help
P.S.: Username and Password are 100% correct → first try works
