uSync.Complete issues synching 2 out of 3 servers

We are using Umbraco 15.3.1 trying to use our usync complete publisher functionality to sync between servers , so far we have been able to snyc between 2 servers with out a problem, but the third, keeps giving the following error. The Export phase completes ,but as soon as we hit the Push phase it gives this error. We cant tell if it is choking on a specific file or if there is some kind of setup that we have not completed for the third server.



Hi,

It might be worth seeing if there is an error on the target server (there might not be, and infact if there isnโ€™t that might also point to something).

I suspect itโ€™s file upload sizes of media or something when itโ€™s being pushed to the server (this would usually respond with a 413 code, but we are still working out some of the best ways to ensure things like that appear in the logs).

We have some docs on upping the upload size - this might fix it:

It could also be firewall, if the third server is behind something like a firewall or azure front door, then it might be that the POST requests containing files (specifically zip files) might be getting blocks.

some docs on firewall issues :

if there are no errors on the target server this is a good indication that itโ€™s one of these things because the block is happening before umbraco actually gets the request, so it points to config.

if you like living on the edge there is a nightly version that will at least give you the response code with that error :

my money is on 413.
