Trying to connect to a buddy's server using 0.15.40 on Mac, for a long (LONG!) running Seablock game. Plenty of mods, but that doesn't seem relevant here.

Browsing multiplayer games doesn't work due to an SSL issue (see screenshot), and connecting directly also doesn't work because of an auth server issue.

Here's a log excerpt:

This is unfortunately expected and intentional. Due to some necessary changes, we had to change our SSL certificates and they now require SNI. The macOS 0.15 and older versions of the game had an issue, where they wouldn't work with SSL that had SNI. Due to the percentage of our players on macOS on a non-latest stable version being very low, I decided to go through with this change, but that meant having to drop not only the matching server for these players, but even the mod portal and automatic updater. There is a possibility of finding a workaround and I will look into it, but I can't promise anything.

We managed to get it working by connecting using IP address instead, and also disabling auth checking on the server.

... and then an hour later we launched the final Seablock component, so at least the two of us are unlikely to play 0.15 on Mac again.

Thanks for the response!
