You might want to upgrade to a later weeWX version, at least 3.7.0, as there have been a number of changes to bin/weewx/station.py (the module that handles station uptime and server uptime) since your 3.6.1 version. I had a quick look at station.py just now and cannot see any one change that would obviously fix your issue but the changes have been substantial. You could probably just download the current station.py from the weeWX github repo master branch and replace your current station.py. Something like:
$ wget https://raw.githubusercontent.com/weewx/weewx/master/bin/weewx/station.py should download the current file. If you do take this approach make sure you keep the old file in case you need to revert. WeeWX will need to be restarted after such a change.
