server file failed to load error

Hi,I am suddenly seeing the following error when the end users try to update my application.Error trying to save file: Error downloading "http://www......../wyserver.wys": The underlying connection was closed: An unexpected error occurred on a send.This happens for all three of my applications that use wyupdate.Can anyone point me to the possible causes?

The files are available on the the server and can be manually downloaded without a problem.

Thank you in advance

Updates on the issue:Found out that the server was replying with a 302 file has been moved to https://.The original request was with http://.

Created new test project using a https:// file request, build and uploaded updates.Wyupdate now fails again with the same indication "An unexpected error occurred on a send".Investigating with wireshark I see the the following https message series between wyupdate and the server.SYN from clientSYN ACK from serverACK from clientClient HelloACK from serverRST ACK from serverWyupdate seems to try 4 times using remote ports 10165-10168.I checked with my host and they confirmed that these ports are blocked but they cannot open them for all ip's.Is there a recommended solution for this problem?

wyUpdate only tries on the ports you specify. It sounds like you either have a proxy that's doing something funky and/or you'r using a custom version of wyUpdate (don't do that -- only use our build of wyUpdate, we don't support custom versions).

Hi Wyatt and thank you for the reply.I do not use any proxies and use a standard wyupdate version as generated by wybuild when I build the updates.I understand that the problem is on the server side but trying to find a solution.When asking my host to open these ports for all ip's they say they cannot do it.I could send you wireshark message logs if you wanted to have a look.Any help is very much appreciated.

Have you found a solution to this. Everything was working fine for me and then a couple of weeks ago all of my users are getting the same error when trying to update.

Error trying to save file: Error downloading "https://www......com/.../updates/wyserver.wys": The underlying connection was closed: An unexpected error occurred on a send.

Searching for a solution I see that this is usually a server problem. I use Dreamhost as my hosting service and store the files there, however, they have stated that they have not changed anything with the servers or security.
