Connecting to VM using https doesn’t work using SouthWest airlines WiFi

Using Chrome on an iPad and SouthWest airlines WiFi, connecting to a VM using https results in ERR_SSL_PROTOCOL_ERROR. Connecting to exe.dev itself works, as does opening a terminal to a VM.

Using a Macbook: much the same, but a different error:

% curl https://skybrian-links.exe.xyz/
curl: (16) Error in the HTTP2 framing layer

% curl -v https://skybrian-links.exe.xyz/

I believe that some airplane wifi completely block the .xyz TLD. :/
