Every time I use sqlitebrowser, quietly and in the background it is trying to send information to the following address with this message.
"Error when connecting to https://raw.githubusercontent.com/sqlitebrowser/sqlitebrowser/master/currentrelease
Connection timed out"
it is trying to send information to the following address
Its not 'sending' but 'receiving'.
If you click the link (which GitHub has automatically linked, so its a valid link) you'll see it returns the following information:
3.10.1
https://github.com/sqlitebrowser/sqlitebrowser/releases/tag/v3.10.1
This is the current version, and a link to the current version.
This is DB4S's way of working out whether you're running the latest version or not. I presume your firewall is blocking DB4S from talking to the outside world, so yes, the connection is timing out.
If DB4S detects its running an old version, then this dialog pops up:

(using the above collected information)
If you click 'View' and 'Preferences', you'll see a 'check for updates' option.

If you untick this (so there isn't a tick in it .. like this)

then DB4S won't check for updates, won't attempt to download the above file, and won't trip your firewall, and won't display a 'timed out' warning.
@crash1013 - Does that make sense? Are you happier with that explanation?
Closing due to no response. @crash1013 - Feel free to comment back when you return. You can still comment on closed issues.
