Hi @davidc502. First off, thank you for all of your dedication & endeavors to support our devices!
Now, I've identified a bug affecting my device since build r11086 where all my outbound HTTP shows "Connection reset by peer" and my browser displays "ERR_CONNECTION_RESET" from all of my devices. This is affecting my WRT1900ACSV1 device, and I've gone down the line of firmware snapshots and confirmed that this bug was introduced in build r11086 and it continues up to the current build r11398. The SHA256sums all match up for every build I've tried. This does not affect internal LAN communication- only external sites.

curl: (56) Recv failure: Connection reset by peer
To fix the issue I am able to flash the r10899 sysupgrade image, or any earlier build, (must de-select "Keep settings") and then I am able to browse/curl again.
Hopefully this can be fixed! I would really love to upgrade to the current build : ) Happy to file a bug on OpenWRT GitHub if you think it might be in their ballpark instead. Thanks again!
