After two years my online game isn't working for some people. Did something change?

A couple of years ago I put out a daily game called Word Dad (www.worddad.com). It has been running without issue for nearly two years.

About four days ago a friend of mine said the game loads but won't run. He tried to download my data file and the file is not available. He cleared his cache but the problem persists.

I can run the game just fine and the data file is definitely there and working. I thought it was a strange issue only affecting his system, but looking at Google Analytics I see a drop in players four or five days ago. (From an average of about 65 daily players to 42 daily players.) So it seems to be working for many people, just not all.

Oh, my friend and I both play on PC. Another friend tried to play on his iPhone and it won't work for him either.

Have there been any major browser updates or something? Anyone else having issues within the last week?

It seems you have problems with hosting.

Check the server logs to see what's going on.

I'm one of your daily worddad players (past 18 months). Thanks for the he game, and the dad jokes!

The game stopped working for me on android pixel 10 yesterday, on Firefox. There is a certificate problem. It fails in Firefox desktop mode, also, and on chrome.

The failure mode is that there is no response to any input. The initial splash screen is displayed, and that's it

It works with Firefox and Chrome on my Apple airbook, after I skip the certificate problem (NET::ERR_CERT_DATE_INVALID).

(The above shows up as deleted today for some reason).

The worddad.com started working again for me last night, so presumably the cert was updated.
