Error 10054 when publish to Azure from Visual Studio

Question

I have been using a publish profile from Visual Studio to publish my web app for about a year. Over the past week or two the process gets stuck and does a few retries until it fails. The error I am getting is:

C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\Web\Microsoft.Web.Publishing.targets(4295,5): Warning : Retrying the sync because a socket error (10054) occurred.
2>Retrying operation 'Serialization' on object sitemanifest (sourcePath). Attempt 1 of 10.

Points to note:

• Nothing has changed on my network
• The publish profile is version controlled and is the same
• The publish doesn't fail from the beginning. It publishes for a while.
• Seems to fail if the file is bigger than ~10 or 15 MB
• Others who have this issue, seems to be their ISP or their network but it seems theirs fails from the beginning.
• Tried it with two different publish profiles on two different subscription accounts resulting the same problem

Anyone has seen this? any ideas?

Finally, the issue is resolved. I had checked every bit, including calling my ISP, and didn't have any luck. Thanks to @rickvdbosch for mentioning the TCP/IP relevance to this problem that juggled my memory.

A few weeks ago, I upgraded the firmware on my router (as I am using DDWRT). I believe that was the culprit. I did upgrade to the latest DDWRT firmware and I see the issue is gone. It is deploying as before all the drama started.

So if another poor soul comes across this error, wish you luck but be aware of this possibility.
