HTTPIO_PLG_CANCELED in SM59 after upgrade to PI 7.11

Hallo,

we upgraded our PI (test) to 7.10 EHP1.

When setting up a connection in SM59 we get error code HTTPIO_PLG_CANCELED. When we create this connection on our production PI (without EHP1) we do not get any error.

When we want to send a message to this address, we get <SAP:Stack>Error while receiving by HTTP (error code: 110 , error text:

HTTPIO_PLG_CANCELED)</SAP:Stack> in SXMB_MONI.

Can someone tell us how we have to fix this?

Greetings.

Kris
