[Comicbase update does not allow access to Comicbase servers]

It appears installing the new 1903 build fixed the connection issue for me...thanks!

Same as above post...connected to the servers to download the update and now cannot connect afterwards.

[Sidekick issues with CB 2021 update]

Since updating to CB 2021, Sidekick will not "Update database content" or "Save to the cloud"...instead, it displays a "can't connect to server" error message.  This occurs even with antivirus and firewalls disabled and/or uninstalled, and with ComicBase/Sidekick having full permissions through the firewall; occurs when directly connected to the internet connection (not through a router); occurs when connected to a different network (I tried from a friend's home); and even occurs with a fresh install on a brand new machine, again on a different network. 

Interestingly enough, database updates CAN occur within the CB 2021 program itself, just not through Sidekick, which indicates I do have access to the server.  These issues did not exist before the 2021 upgrade and nothing changed with my network/computers since then.  Also, I am not using OneDrive or any similar programs.

I am open to any suggestions as to how to get this resolved -- thanks!
