Provided I did this correctly, it did not work.

Uninstalling both security programmes?

No. The xml file work around. But the security programs would have been next. See further down for my solution.

Thanks for suggestion, JanniCash. I had been wondering the same thing due to an upgrade I remembered that I had not thought of as a possible issue and when I saw your post, I knew it was the solution.

I use, and have used for a while, with things uploading OK, a program called "Hide my IP". When I switched to the paid version, I was able to hide IP on any and all internet applications. But, doing this still did not cause a problem because when I made that switch initially, there was also an upgrade that was there that did not happen correctly, so those changes did not happen. Right before the upload troubles on BOINC, I re-tried a new upgrade to Hide my IP. This time it worked, and my changes were applied. The next time BOIONC tried to upload, that was when the trouble started. I think the few times I saw files go right after I re-booted, there probably was a slowdown in Hide My IP finding a suitable server, so BOINC was allowed to upload until that server was found and applied.

Yikes- Now all files are uploaded. And I have made changes to Hide my IP to allow BOINC to do its thing.

Thanks to all, for trying to help me. I am back in the Seti business.

That makes sense. Hide-My-IP seems to go heavy on proxy and redirecting. I'm not using that sort of stuff as (you already know) I'm doing things even more heavy handed via PF on my firewall. But just looking at their FAQ makes me go "yupp".
