Cannot download or sync certain projects.

[Nathan-LloydBore]

It looks like a firewall in the DrayTek router we use has suddenly started blocking projects (possibly specifically ones with a WMS layer in). Cannot find any further details yet other than that these projects will not sync and cannot be downloaded through the plugin.

I can manually download the project through the web interface.

Not sure if there's anything we can do on our side - I would suggest to whitelist app.merginmaps.com in your firewall to disable content filtering, or disable the content filtering altogether. It may be a good idea to ping Draytek to see what URL keywords are there in their filter... I wonder though how can the router inspect encrypted HTTPS traffic - or are you running on premises Community/Enterprise edition?

[Nathan-LloydBore]

We have disabled the content filtering and created a project without any externally streaming data layers and are getting the same results. The server is a CE server hosted on Microsoft Azure. I am trying to get to the bottom of what the block is but we haven't changed anything ourselves on that front recently to trigger this.
