504 Gateway Time-out as reply for integration event map

[Danny Liebig-Rath]

Hello,

I have created a n integration event solution that creates leads from a mobile app in our on-premise Dynamics 365 system.

The very first test call in the morning always sends a time-out error on reply back to the app even when the solution completes successfully:

504 Gateway Time-out 504 Gateway Time-out

What we saw is that all lookups and tasks in the map take much more time at this first call then at any later time (see attachment).

The first call takes between 50 and 59 seconds, the second one takes less than 20 seconds depending on the size of sent attachments.

Has anyone experienced something similar and could give us a hint, how to solve this timeout or on which side the timeout really happens

 

Thank you in advance.

Oh, by the way: We already tried to remove the cache function for the lookup results which didn't show any effect on the duration of the steps.
